This thread is meant as a modern follow-up, to continue exploring the different properties and characteristics of transverse and longitudinal transmission lines as Eric Dollard's Borderlands-era experiments explored in the 80's:
https://www.youtube.com/watch?v=bNFpJVpm9CsExperimental Setup:* Build a simple Transverse and Longitudinal network using reference below.
* Use the same number and value components for each test (eg: 6ea capacitors valued 0.01uF and 6ea inductors valued at 40mH).
* For real-life experimentation, a simple sine or square frequency generator should suffice for both tests.
* For simulator experiments, use low-impedance drive for Transverse network and high-impedance drive for Longitudinal network.
* For simulator,
https://www.falstad.com/circuit should suffice though you will have to use 1ea high value capacitor in leiu of 2x smaller value due to limitations of the sim.
* Measurements can be taken open-circuit or with a high-value resistance between L1+L2.
Transverse and longitudinal networks will exist in any bulk transmission media. They are inseparable.
Drop a bowling ball into a calm lake and you will generate two waves. One will be a transverse wave that travels along the surface and ripples slowly outward. The other will be a longitudinal wave traveling through the lake at great speed, that is undetectable on the surface. Both waves clearly have very different properties.
Observations to note: * Compare 1/4 wave resonant frequencies of both circuits
* Find the ratio between transverse and longitudinal resonant frequencies. It should approach a very specific geometric ratio.
* Compare the Q factor in both networks.
* Observe differences in voltage magnification at the end terminal.
* Observe the phase relationship between voltage and current at the end-terminal in both circuits.
* Add a leakage resistance/conductance to each circuit element and see how it affects losses in both circuits.
* Add a series capacitance, resistance, or inductance in the middle of the transmission line and observe how it affects the frequency and performance of both networks.
* Determine the propagation velocity of both circuits using 1/4 wave resonant frequency. (this one is more dramatic in a real-life network).
I am happy to help anyone who wishes to replicate this work and understand the potential ramifications of it (of which I've barely scratched the surface).
