Preparing electromagnetic wave to travel in waveguide or  its special kind the INTERFACE:


Tesla Tower is an air transformer.
Air transformer is the transformer that is made from  coils only with no metal core
The core of the transformer acts as a support to the winding in the transformer. It also provides a low reluctance path to the flow of magnetic flux.
The core of the transformer  in modern times is made  no longer from permalloy plates  but from  ferrite material and is usually  in form of Closed  Loop.
Permalloy is a nickel–iron magnetic alloy,  with about 80% nickel and 20% iron content.
Closed Loop is  shape of core making magnetic  flux to be able to  travel in it.
However one of secrets of  replication of Dr James Corum device is use of ferrite bars.</sub>
That experimentation and learning curve is  mandatory step needed to learn how to extract energy from Schuman  Waveguide and this is our  FE.
I'm probably not going to talk about it at all or in very much critical moment of my writing. !!!!!

PHASE<sub>:
There are two different factors  of phase not directly related but related in time sequence:

a.-
Phase relation in Tesla Coil
Explanation:
In Tesla Coil we are dealing with standing wave
Standing Wave
is a wave which oscillates in time but whose peak amplitude profile does not move in space.
https://en.wikipedia.org/wiki/Standing_wave
That wave will oscillate vertically between Top Capacitor of Tesla coil and  the ground.
Top Capacitor is a top plate on the top of Tesla coil forming  capacitor  with another plate- the ground.
b.-
The complex longitudinal propagation phase constant along the Earth's surface for the Zenneck surface wave
Explanation:http://www.tfcbooks.com/articles/tws4rev1.htm</sub>


Conclusion:
<sub>We have few  ways to  make  Wave tilt into  Complex Brewster Angle  ( in our case this would be complex  Brewster Angle)
We can do it by:
-lowering or lifting up the Top capacitor
-or playing with the  phase.


source of information:
there is plenty in my writing about :
-Complex  Brewster Angle
-and phase relation.

POLARIZATION


To explain what is polarization and why it is important to us  we need to to touch some basic knowledge 
and point at similarities to visible light.

The visible spectrum is the portion of the electromagnetic spectrum
that is visible to the human eye. Electromagnetic radiation in this range
of wavelengths is called visible light or simply light.
A typical human eye will respond to wavelengths from about 380 to about 750 nanometers.

https://en.wikipedia.org/wiki/Visible_spectrum
Light is electromagnetic wave and has frequency measured in Hz or nm.
Electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields.


Our wave we use to transfer from point A  to point B is :
-  exactly  the same  electromagnetic wave but differing from light  with frequency
Our wave we extracted  from Schumann Waveguide by our receiver  is:
-  also  exactly  the same electromagnetic wave but differing from light  with frequency
That  electromagnetic wave  is invisible to our eye acting as receiver only to visible light .

_________________________________________________________________

EYEGLASSES:

When we use polarized eyeglasses  we  let only some form of light to be seen by our
eye acting as  the receiver.https://en.wikipedia.org/wiki/Glasses

Polarization is lossy _{but not always  as much:
energy loss can be partially avoided with the use of special filters, with the same filtering effect
but that, based in a different filtering technology,}

Active polarization filters, which use an active electrostatic field
to polarize both the fibers of a media pad

POLARIZATION
_{we continuing with  explaining polarization}

_________________________________________________________________
Polarization of  Electromagnetic Wave

An electromagnetic wave such as light consists of a coupled oscillating electric field and magnetic field
which are always perpendicular to each other; by convention, the "polarization" of electromagnetic waves
refers to the direction of the electric field. In linear polarization, the fields oscillate in a single direction.

_{https://en.wikipedia.org/wiki/Polarization_(waves)}

So in every  electromagnetic wave we have oscillating :
electric field
and
magnetic field
which are always perpendicular to each other

_________________________________________________________________
Let's look at  source of  electromagnetic radiation from perspective of polarization.


POINT SOURCE:
_{https://www.bing.com/search?form=MOZCON&pc=MOZI&q=point+of+source}
source of light can be considered a point source if we have e.g lightbulb.

_{We can draw spheres  around it to image  this radiation.
Light as electromagnetic wave is radiating in all directions in space around it equally and this radiation is called spherical}

LINE SOURCE:
_{line source, as opposed to a point source,   is a source of electromagnetic radiation that emanates from a linear (one-dimensional) geometry.
Source of light can be considered a line source if we have e.g fluorescent light bulb 2ft long.
-if we place this fluorescent lightbulb vertically we can see that  light is not radiating to the top and the bottom  of it but is seen all around  it.
We can draw  cylinders  farther away all around this fluorescent  2ft long lightbulb to image  this radiation.Light as electromagnetic wave is radiating
equally in cylindrical pattern in space around vertically  placed fluorescent lightbulb 2ft long 
and this radiation is called cylindrical}

_________________________________________________________________
VERTICAL and HORIZONTAL POLARIZATION

<sub>if we now take this vertical:
-  2ft long  lightbulb
   or
- vertical antenna
   or
- vertical Tesla Tower
We see that this  cylindrical pattern of radiation is at 90 degrees to the horizontal ground.
We call it</sub> Vertical Polarization.
Note:  in vertical antenna we have vertical polarization but electromagnetic
           wave is propagating horizontally farther away from it.

--------------------------------------------------------------------------------------------------
_{Although  Tariel Kapanadze didn't use obvious vertical polarization
our experimenter  would use  vertical polarization only.}
---------------------------------------------------------------------------------------------------
_{Propagation of electromagnetic wave in Free Space always suffers significant losses  due to Inverse Square Law.
https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560251/#msg560251
However Inverse Square Law doesn't apply to Waveguides:}

Below you have:
- point source  _{having spherical pattern of radiation}
- line source    _{having cylindrical pattern of radiation}

_{Electromagnetic Wave in form of:}
STANDING WAVE

So far we  learned that:
<sub>- our Tesla coil must be  vertically placed to the ground  and by that have vertical polarization to the earth/air INTERFACE.
    earth/air INTERFACE is explained here:
    https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560166/#msg560166
- between Top capacitor and Earth we have standing wave
    standing wave https://overunity.com/18335/wireless-energy-transfer-experiments-builders-board/msg560291/#msg560291</sub>
   

The most common cause of standing waves is the phenomenon of resonance,
     in which standing waves occur inside a resonator due to interference between waves
     reflected back and forth at the resonator's resonant frequency .
     For waves of equal amplitude traveling in opposing directions, there is on average no
     net propagation of energy .

     standing waves

_________________________________________________________________

    _{The difference between standing wave and traveling wave is:
a- Traveling Waves transport energy from one area of space to another, whereas standing waves do not transport energy.
b.-points on a standing wave oscillate in phase, whereas on a traveling wave only points a wavelength apart oscillate in phase
    - the rest on that wavelength oscillate out of phase with the original point
c- Standing waves occur in confined spaces – in a microwave oven, on a violin string, or in Tesla coil between Top capacitor and  earth.(valid for  all types of SW)
    The waves interfere as they move about within the space to set up a series of nodes, or points of minimum vibration, and antinodes or
    points of maximum vibration. The most striking feature of standing waves is that they only occur for certain frequencies.}

-Node (physics) A node is a point along a standing wave where the wave has minimum amplitude.
-Anti node- (physics) An anti node is the position of maximum displacement in a standing wave system.
One characteristic of every standing wave pattern is that there are points along the medium that appear to be standing still.
These points, sometimes described as points of no displacement, are referred to as nodes.
There are other points along the medium that undergo vibrations between a large positive and large negative displacement.
These are the points that undergo the maximum displacement during each vibrational cycle of the standing wave.
In a sense, these points are the opposite of nodes, and so they are called antinodes.

The example of standing wave in transmission line is presented here:
https://www.youtube.com/watch?v=M1PgCOTDjvI
_{Transmission line : is any piece of wire  or conductive path  delivering signal to the radiating this wave element  like an antenna, or Tesla coil and that will be our load that  sends this energy OUT.
  e.g: generator sends signal  using transmission line ( wire. coax etc.) to an antenna.
If impedance of that antenna  is matching impedance of  transmission line and impedance of  generator than we are able  efficiently
to send its energy without standing wave  to an Antenna.
We may also send energy of the generator to the resistor e.g 50 Ohm and dissipate  energy of  the generator without standing wave if  it matches
the  impedance of the  transmission line and  impedance of  generator.   
There is no dissipation of energy due to resistance in  ideal LC  circuits.}

conclusion:
<sub>If we  want to send energy from point A to any point B we need:
- to have  energy from Generator delivered using transmission line to  the Tesla Coil
-we don't want any standing wave  be caused by impedance miss-match  of  generator and transmission line
and if we had  no  standing wave in our antenna (Tesla Coil) this energy would be  taken by that antenna 
and radiated into the free space around us. https://www.allaboutcircuits.com/textbook/alternating-current/chpt-14/characteristic-impedance/
However  we don't want that either..


We want  our energy from generator to be delivered to Tesla Coil and than we want to
tilt  that energy by another means- (another form) of polarization .
we don't want this energy  to go to the Far Field https://en.wikipedia.org/wiki/Near_and_far_field
We want this energy to land at Complex Brewster Angle in the INTERFACE ( Earth/Air)
And the magic word here is word COMPLEX.
It's complex phenomena having Brewster  angle  as  one of its elements</sub>

So far we were talking about physical polarization of an antenna ( Tesla Coil)
Any vertical  to the ground  antenna  radiates  all around  and wave  spreads  horizontally in cylindrical pattern .
but because   the antenna is  vertical than  wave radiated from it will be  vertically polarized
So polarization of  the   electromagnetic wave depends from physical position of  our Tesla coil with reference to the ground .

Polarized electromagnetic wave :
polarization  of the wave represents how the electromagnetic waves are physically oriented in space.
