Part 3
propagation - of the wave
The path taken by the wave to travel from the transmitter Tx and reach the receiver Rx is known as Wave Propagation
the same is  with  waveguide and  interface is a special form of  a waveguide.

Goubau line shown in picture  in Part 1 192002/image//   is made from wire  covered with dielectric ( e.g Teflon)
this is also   a form of an interface that belongs to waveguides.
Electromagnetic wave travels in the 2D space between  wire ( conductive medium) and Teflon ( the dielectric)

When we deal with  regular telephone line  or  electrical power line we  have likely  AC there but
that AC can  consist of two or more signals having different  frequency .
these signals will not interfere with each other  and will remind  independent.

That is very important when we start to talk about PLC or PLCC.
At the end everything will  come back to Tesla  Coil and Energy.
I hope am not talking to much

Wesley,

What an education you provide - an inspiration!

Thank you,

Par4:
waveguide:
Imagine that you have a metal tube or other device confining and conveying electromagnetic waves
It can  be compared to a water pipe- the water can only go  inside the pipe;
If the pipe is flat, rectangular, line disc or look like  double sphere  with space in between - the water travels in every  part of that space.
The same story is with  waveguide  that can have different shape and  electromagnetic wave travels inside of it.
https://en.wikipedia.org/wiki/Waveguide

Space between Earth and ionosphere  is a waveguide too.
https://en.wikipedia.org/wiki/Earth%E2%80%93ionosphere_waveguide
We  with all living organisms are inside of that waveguide.
The electric and electromagnetic activity inside of that waveguide called also Schumann waveguide is explained here:
https://en.wikipedia.org/wiki/Schumann_resonances

Waveguide made from Conductive and Dielectric material:
A very special form of a waveguide is  a waveguide that doesn't have empty space inside and is made  from conductive medium like  copper and dielectric like  Teflon
That structure  looks like a wire with  isolation on it. We may call that space between the two materials -  the 2D space (two dimensional)
But for electromagnetic wave at suitable  form( called TM mode) and right frequency  this 2D space  is an open highway .
https://en.wikipedia.org/wiki/Goubau_line

Yet another 2D waveguide is a e.g. aluminum foil on the floor. or grass. or  soil that is conductive like wire  and on the top of it is air that is dielectric.
So we have the very two materials needed to form our "flat" waveguide.
We don't need  Teflon  or other  dielectric any longer as it is too expensive for us.

Earth is not so good conductor but still some sort of lossy conductor  and we have Air that is  a dielectric
And 2D space between the two is our highway for electromagnetic wave.

Summary:
Because - the space between Ionosphere and  Earth is /makes( Schumann waveguide)
and 2D space between  air and earth is another  waveguide than  we may try to  move some  energy e.g.
originated  by lightning strike, to move to that second waveguide and  than extract it from there and use it for ourselves..
If we are able to do it  than we have  our electrical Energy For Free

Part5
Impedance:
Impedance exists only for AC and doesn't exist for DC.
https://en.wikipedia.org/wiki/Electrical_impedance

That is why Thomas Edison lost battle with Nicola Tesla aver electricity 
https://www.energy.gov/articles/war-currents-ac-vs-dc-power
tesla-vs-edison-compariso



And everything is about impedance:
example:
longer wire -  more resistance to DC and to AC too.
But coil , electromagnet, door strike, or relay made for AC has a lot less wire  than for DC.
If we connect such AC relay to the same voltage but now DC we may burn it very fast because resistance
of it is to small.
Impedance is like a resistance but exists only for AC and when  added to the small resistance of short wire
in that  door strike it  makes it  together  large enough.
Because resistance is always present and is steady factor for AC and for DC we call it REAL- component
Because impedance  exists only for AC and is not easy to measure we call it IMAGINARY component
That impedance is made from two "subcomponents" capacitive reactance X_c and inductive reactance X_L
Impedance depends from frequency and is highly reactive. That is why we call it reactance
So now we know  that Transformer works only with AC mainly due to it.
https://www.explainthatstuff.com/transformers.html


Impedance may need to be matched :
Example: metric bolt doesn't work with  imperial nut.
You may try to  screw it too but you will damage both.
So you need metric nut and these nuts have different diameter too.

Impedance is measured with Ohms .
If  impedance of your  Tesla Transformer is  250,000 Ohms
and impedance at the output of your generator  powering it is 50 Ohms,  we need to match it.= make   both exactly the same (like that bolt and a nut.)
For that we need to use  a Tuner.( it is often a matching transformer with  switchable length of  the winding  X_L and  capacitors X_c)
.electrical4u.net/transformer/transformer-impedance-calculator/#:

Ferrite core transformers are widely used in RF transformers, especially for current balancing see below and impedance matching
for TV and radio antennas. Because of the enormous improvement in inductance that ferrite produces, many ferrite cored
transformers work well with only one or two turns.
https://en.wikipedia.org/wiki/Transformer_types


Summary:
So impedance applies to both  the regular electric circuits  like our  electrical system in our house and to
electromagnetic circuits antennas waveguides and so on.
However the lower is the frequency the lower is requirement to match impedance of the circuits.
And  frequency of our electrical grid is  50 or 60 Hz

Now we may think why Tesla, Dr James Corum, Kapanadze used so low frequency
( simplified explanation) -Well the lower  the frequency the lower are all loses and electromagnetic wave  travels more far around the earth .
and if you use a waveguide than  losses are really small.
I do stress that inverse square law  doesn't apply to waveguides..

Part 6
practical  advice about instruments and methods  used to match  our Tesla Coil, and other circuits may
provide answer Why  our Kapanadze or SR or  antennas, resonant circuits,   etc. never worked
