    You don't need CERN. All you need is a piece of wire of known length, a function generator, and an oscilloscope or voltmeter or ammeter.

    Meyl is measuring one resonant frequency, assumes that propagation to equal the velocity of light (it's not. EM waves only travel at the velocity of light in a vacuum, not through the conductors of a coil), and then measures a second resonant frequency then concludes that the propagation is "faster than light" on that basis alone. I assume you've heard of harmonics. Also, longitudinal waves is not "scalar". The mathematics for that is given in Eric Dollard's quote above.

    When you know the length of a conductor, then you can calculate the propagation velocity of a wave travelling along it from the amount of time it takes to reach the other end.


    New Extra Coil #3:

    Diameter = 8.28cm
    Height = 8.28cm
    93.25 Turns
    Conductor Length = 24.256 Metres
    Luminal Wavelength = 97.024 metres
    Luminal Frequency = 3089.879 kc

    Free Space Frequency = 5778.074 kc

    Measured Frequency:
    Direct connection = 3676.7 kc
    10pF coupling = 3990.5 kc

    Free Space Propagation = 187%
    Measured Propagation (10pF coupling) = 129.14% velocity of light
    Measured Propagation (direct connection) = 118.99% velocity of light
    Diameter: 8.4 feet
    Height: 8.0 feet
    Number of Turns: 100 numeric
    Mean Length of Turn: 8 meters
    Total Length of Turns: 800 meters
    Luminal Wavelength: 3200 meters
    Luminal Frequency: 94 Kc/sec
    Free Space Frequency: 176 Kc/sec
    Actual Frequency: 116 Kc/sec
    Free Space Propagation: 187%
    Actual Propagation: 123%
    There's no actual faster than light velocity involved. The propagation velocity of the coil is "faster than light" because the wave travels from one turn to the next rather than following the whole length of the conductor all the way around, giving the result of a higher resonant frequency than one would calculate from the wire length using the conventional frequency/wavelength/speed of light relationships. The propagation velocity is dependant on the geometry of the coil.

      Your link to the old Dollard stuff is of little value in relating Tesla Coil analysis to Electrodynamic Theory and Maxwell's Equations, but thanks anyway.

      The following papers I find far more instructive in advancing the Tesla <=> Maxwell integration.

      RF Coils, Helical Resonators and Voltage Magnification by Coherent Spatial Modes
      K.L. Corum and J.F. Corum, 2001

      Abstract – By modeling a wire-wound coil as an anisotropically conducting cylindrical boundary, one may start from Maxwell’s equations and deduce the structure’s resonant behavior. Not only can the propagation factor and characteristic impedance be determined for such a helically disposed surface waveguide, but also its resonances, “self-capacitance” (so-called), and its voltage magnification by standing waves. Further, the Tesla coil passes to a conventional lumped element inductor as the helix is electrically shortened.

      A Technical Analysis of the Extra Coil as a Slow Wave Helical Resonator
      K.L. Corum and J.F. Corum, 2014

      Abstract - In this paper, we present an analytical development of the Extra Coil as a top-loaded slow-wave helical resonator. Our treatment starts with a foreshortened coaxial resonator whose inner conductor is constructed of an end loaded spiral delay line. We develop formulas for the slow wave velocity factor and characteristic impedance of the equivalent transmission line which are valid as the outer walls of the resonator recede to infinity – leaving Tesla's ‘open coil’ resonator above ground.

      The Voltage Standing Wave Ratio (VSWR) is then analyzed, including losses, and the voltage step-up of any distributed Tesla Coil resonator is obtained. The resulting model not only predicts the resonant behavior of the Extra Coil, but readily permits its representation on a Smith Chart. Several examples of Extra Coil analyses are presented numerically, and displayed on Smith Charts. Specifically, the November 1, 1899 and January 2, 1900 Extra Coils of Tesla's Diary are discussed in detail and are shown to produce voltage step-ups on the order of 10 to 15 megavolts.

      The model also serves to explain how Tesla tuned the RF portion of the Colorado Springs apparatus and is shown to be consistent with specific Diary instructions by Tesla.'s_Extra_Coil_6.24.14 .pdf

      With respect to Tesla Transformer/Coil design parameters there are a wealth of On-Line Tesla Coil related papers, articles, calculators and so forth, including even some Android Apps; so Eric's lumped element approach has become a bit redundant. For example:

      The Zeus Tesla Coil September 2011
      The Zeus Tesla Coil - Theory of operation | Hazardous Physics

      Deep Fried Neon - various on-line Tesla Coil related calculators
      DeepFriedNeon - Tesla Coils

      Tesla Coils 4 Christ
      List of Tesla Coil Formulas

      Tesla Coil Design, Construction and Operation Guide

      The list of sites is long and diverse...

      My impression has quickly become you are more interested in defending some sort of position/belief, or simply posting for the sake of posting, and since I have no idea what it is; ===> I will just say 73's my friend...

        Funny, you tell me to check my sources, but you do not check yours. Prof. Bruhn's response was to an early version of Koens theory while he was in the process of developping it. It was not a particular fair move of Bruhn to reply to Koens request to review his work in the way he did. The flaws that have been found have been corrected in the paper that I linked. This work IS mathematically correct while Meyls tragic attempts are not, as I have pointed out elsewhere on this forum. Besides his mathematica incompetence his practical work is also flawed, as dR-Green already pointed out. His two coils are connected by a "ground wire" and you can easily verify that a current is flowing through this wire between the coils. (which I have done)
        To say that it proves the existence of his magical rays is as ridiculous as saying that when I flip the light switch, magical rays will transfer energy to the light bulb. Rays that you can not detect. And all that while anyone can see there are wires running from the switch to the light bulb. That is what Andre Wasser is saying too. It is illogical and unreasonable to assume any other proces to take place as it can be explained completely with known physics.

        Solarlab, you funny guy, did you replicate Meyls experiments? Do you understand vector algebra? Did you ever build a working Tesla coil with a so called "extra coil"?
        Something tells me that the answer to all of these questions is "NO", and yet you feel you can come here and argue with people who can answer "YES" to these questions.
        And you talk about "science spammers"?
        I also like this one:
        Check your FACTS and SOURCES before attempting to inject your opinion as if your some kind of guru with "EXPERT KNOWLEDGE"...
        Something about pots and kettles comes to mind.

        If you can not find my (or dR-Greens) earlier comments on Meyls (is NOT Tesla) shoddy rubbish, here is a 3 minute video that I made about it a long time ago. I think I have spend more time on this man than he deserves. I am going to leave it here.

          Curse of the Ever Curious Expanding Mind!

          So as not to leave this discussion dangling, I will leave you all with some (IMHO, higher level). what I will call, base information.

          It's probably good practice to consider many views, opinions and approaches to a subject or problem; with an open
          mind - often times there are many correct answers and solutions! However, as you all know, picking the best "one" for
          the task-at-hand can be a daunting challenge... Good luck and Happy Holidays!

          LONGITUDINAL - SCALAR WAVE briefings:

          What Are Scalar Waves? Horst Eckardt, 2012

          Abstract: There is a wide confusion on what are "scalar waves" in serious and less serious literature on electrical
          engineering. In this paper we explain that this type of waves are longitudinal waves of potentials. It is shown that a
          longitudinal wave is a combination of a vector potential with a scalar potential. There is a full analogue to acoustic
          waves. Transmitters and receivers for longitudinal electro-magnetic waves are discussed.

          Includes a good discussion on transmitters and receivers of longitudinal waves and suggestions relating to the
          Faraday Cage test. Also points out that the speed of propagation depends on the form of the waves, and; to
          quote "There are rumors that Eric P. Dollard found a propagation speed of longitudinal waves of pi/2 times c
          (where c is the speed of light) but there are no reliable experiments on this reported in the literature."


          What is the difference between longitudinal and transverse waves?

          What Is Seismology and What Are Seismic Waves?

          The introduction, Basics, deals with Math and Physics Terms and Symbols. Chapter 6, "Wave Equations," discusses
          Transverse and Longitudinal waves, displacement current and the Nature of Charge. The text presents both (almost
          introductory level) descriptive narration along with the pertinent mathematical equations.

            Most of your links given have been discussed on this forum at some point, someplace.

            dR-Green, Ernst and a few others have had successful practical results with Tesla coil apparatus.

            I would advise not to go down the Meryl path, as they have advised.

            As a basic principal, the Earth terminal or the neutral wire of the coil is the output of the coil, not the terminal capacity at the top. Ė It is the reflection, the reflected wave. The rate of variation of the dielectric field gives rise to a displacement current. Ė This is the basic one wire principal.

            When youíve lit a 240V filament bulb with one wire, with your body as a counterpoise, then youíll begin to have a basic understanding on whatís going on and how it works..


            BYW Iíve lost count of the number of times, but there is no such thing as a Scaler wave. If its scaler, itís constant all pervasive, it does not vary, so it cannot be a wave.

            A scalar flux, scalar potential or scalar field - okay, but not a scalar wave!

              Hi Sputins,

              You don't happen to know the missing piece of Maxwell's equations, or anything else that might help in completing a correct simulation of the Ruslan/Akula/Smith or Meyl type devices using CST or HFSS by chance? A modified Traveling Wave Tube type model using CST comes pretty close but there appears to something a bit different - of course I'm aware of the physical and technical differences but the results do get (a yard!) close to at least the measured Ruslan device. One ray of hope lies in the SW analysis on the Ukrainian site I posted.

              The devices work for the most part as required, but without a correct EM model, development has become nothing more than the old cut and try brass-board routine. I've scanned many forums and only the Russian fellows seem to be even looking at the mathematics to any extent. Without a model its damn tough optimizing these devices.

                This, in a nutshell, was the reason behind my original post. The haphazard development by numerous prior inventors and by all of us on here is one gigantic exercise in shooting in the dark. It's time-consuming, expensive, and frequently frustrating. If there were some theoretical or mathematical models that could be used to guide development it would sure help a great deal. Apparently numerous theories either extending or replacing classical electrodynamics have been advanced: does anyone know which, if any, have been experimentally verified, or even what kind of experiment could be used to verify and/or discriminate between the predictions of the various theories?


                • #23
                  I do not think of experimental research as shooting in the dark.
                  Most current theories have their flaws but to arrive at better theories you must try to collect as much as possible experimentally proven facts. Using these you can develop a new and better theory and with that you can create supporting math.
                  That is, IMHO, how it should be done.

                  But today people seem to be working the other way around.
                  They develop their math first, based on existing material. They (often) skip the phase that would provide a theory about the underlying mechanism and then they try to set up experiments to find support for their mathematical models. This is obviously a very wrong method that could support the wrong models for a very long time. (as we frequently see).

                  The Maxwell equations are an example of this. They contain a blatant error. But since almost our entire physical understanding is based on these equations no one wants to even consider replacing them.

                    Tesla Coil - two seperate processes - interesting...


                    Vyacheslav Gorchilin's note entitled "The lumped and distributed resonances in the inductor" discloses an interesting phenomena with respect to the Tesla Coil. Here is an extract from the note:

                    " If DL (long line or Tesla coil) put in parallel to the capacitor C1 (Fig. 1.2), it will begin to work one process, almost do not affect the wave. It is obvious that in this case we are dealing with an oscillatory circuit, the inductance which is the inductance of the line segment DL. I.e. a second, independent model, which can be easily calculated by the classic formula of Thompson (1).

                    Now it is easy to imagine what happens if we turn this long line in a coil — slightly changes its own capacitance and inductance, and two of the process and will work almost independently from each other. By the way, in this case, the wave model is better to rely on more precise formula, presented in [1].

                    Why are these processes, and thus their models, are independent? Look at figure 1.4, which shows their equivalent circuits. DL is in the standing wave, and since R1 is much less than the wave resistance, wave — almost no losses (right). On the wave process capacity C1 does not render almost any influence, but it forms with the inductance DL RLC circuit, which in turn also works independently (left figure). Changing C1 also has no effect on the wave process, but completely changes the picture of the LC resonance.
                    According to the author, the independence of the processes due to their work in different reference systems. The assemblage point, or point of combining these two systems is the load R1.

                    For skeptics who believe that in the coil (or in a long line) can't go two independent processes at the same time, a simplified model (Fig. 1.3), which added another DC power source E2. It is bridged by a capacitor C2 to a lower internal resistance at high frequency. As you can see on R1 we get the constant offset from E2, and independent of the antinode of the current standing wave from E1.
                    " {Emphasis in green added.}

                    Reference: The lumped and distributed resonances in the inductor

                    Reference [1] from notes: Alan Payne "Self Resonance in Coils" at

                    This may be enlightening since CST and HFSS can easily combine "separate processes." Collectively these processes are at odds when intertwined, so to speak, which increase the simulation time and complexity beyond reason (several weeks when using a complete, fine, tetrahedral mesh on two networked 4.2 GHz overclocked i7s).

                    But separating the processes may solve two big problems at the same time! And prove to be of fundamental significance!

                        In other words, whatever is at work producing a charge on the capacitor's second inner terminal (separated from the first by dielectric within the cap's Faraday Cage casing) cannot be conventional electricity?
                        Must be from the ambient/vacuum?
