Title:
Wireless Energy Harvesting by Direct Voltage Multiplication on Lateral Waves From a Suspended Dielectric Layer

Link: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=8053760


From  part  #1  we have learned   that
-earth as    multilayered part of interface  is suggested.
-that is  in line  with Marconi's early experiments,
-the paper explores the feasibility of wireless energy harvesting by direct voltage multiplication on lateral waves.
-we could also look at  picture  representing multilayered  interface
-  we  had the first look at wave behavior while  "loading" into  interface

From  part  #2  we have learned:
- the  differences  between  regular EM wave known also as Space wave and Surface wave.
- the 4 layer suggested   ground  as one of parts of interface Air/Earth
- the wave  in  the  interface  must  be  in TM  mode

From  part  #3  we have learned:
-  that  the thickness of both layers  of the  interface is expected  to be 1/4 of  the  wavelength Y

From  part  #4  we have learned:
Basic schematic   of  Avramenko fork and  voltage multiplier   that can be used at any frequency
in association with Goubau line or any other type of interface.

From  part  #5  we have learned:
SIMULATED AND MEASURED RESULTS OF BASIC WPT (Wireless Power Transmission)CONFIGURATION
We can see from Fig.3b Fig.3c impressive performance   of TM in the interface.
=======================================================

lateral waves can significantly increase the energy efficiency due to less signal attenuation compared with space waves, therefore,
WPT based on lateral waves can be used for simultaneous charging of the sensor nodes more efficiently
without causing harmful interference to wireless communications.

-this above is another confirmation of expected performance over the regular  EM wave

In addition to inherent nature of lateral waves for interference reduction, the delivered power by lateral waves canalso
be conveyed on a lower frequency channel

.

The power can be preferably delivered at a lower frequency,say at any frequency below 500 MHz, where a highly con-centrated lateral wave is easier to form.

-this above is another confirmation of expected performance TM  in the interface at low frequencies.

delivered power does not impose any interference to the received signal, the energy to be processed by the receiver
at the receiving end can be pre-filtered with a high pass filter. Fig. 5 illustrates this scenario.

-this above is another confirmation of fact that this wave is not  present in Far Field 
_{The exact  statement  saying  it  is int the article I just must have time to find it}

Summary from all 6 parts:
I did not yet write  it. 
Just  lack of time
but in overall it  kills most if not all of  the skepticism

Im just looking for some suggestions.

I have in my possession   EIN model 500L .
After reading some posts i find recommendations to use EIN 3200L $$$$$ .
https://overunity.com/17735/wesleys-kapanadze-and-other-fe-discussion-forum/msg536259/#msg536259
For now ill try to stick to Tesla coil concept and not corums polyphase probe type of structure. ( Unless 500L can be used successfully )
My amp is very low power some 300mW and i wonder if this can be used to switch a transistor 2SC5200  for example.
It should be good for 2-500 mhz but i see a lot of distortion at higher frequency, maybe poor cables.
The goal  is to use signal generator ( variable frequency ) to power a solid state tesla coil in simple way. (2-3 Mhz)
kind of like slayer exciter but variable frequency. 
Any schematics?
Thank you for all the help.

It can only be used as preamp.
You need significant power.
But Ham radio TS-2000 can be used at its low 1.8MHz.The prestige Transceiver .
or any other Transceiver.Some of them can be on Ebay for less than $100 or go to Hamfest
Be careful as you at first need to use it at CW short impulses like from electronic Morse Keyer and let it rest.
You may damage it at no time due to  impedance mismatch

SWR meter is needed to most of them.
Note:  use of these transceivers requires FCC license.But you have rights to own it .

Why do you need a power amplifier? Each tesla coil is your amplifier and transmitter. As a last resort, you can use the music version of the tesla coil!
