The article  in first section   is talking about  history:
1.Theoretically predicted   by Maxwell  in  "A  Treatise  on Electricity and Magnetism" and  experimentally  confirmed  by Hertz,  wireless  power transfer  1888.
2. Application  of inductive  coupling  and capacitive coupling was done by Tesla
   for the purpose of presentation in his South  5th  Avenue  lab.
   it was  a single  loop  of  electrical  cable  suspended  from  the ceiling around the perimeter of a Tesla's large room,           
   inside of  which were  multiple receiving coils.
a. From1891 to 1898 Tesla   demonstrated   the   resonant inductive coupling   (called  at that time - the electrodynamic      
   induction)   and   the capacitive   coupling   (or   electrostatic induction)   near-field wireless  power  transfer  techniques,.
    The  presentation was kept (both) privately  .
b. the same presentation from  point a.  was done in New York  laboratories  and  during  presentations  in  New  York,   
    Chicago, St. Louis, Philadelphia, London and Paris.
c.  to explain the phenomena he used  wording:  'effects of a damped  character'  and 'circuits  which  radiated  rapidly.'
d. in 20tieth  century  Tesla  developed  technique  in which the radiation resistance  is lowered and the production 
    of electromagnetic space waves is suppressed.
3. Based on it Tesla constructed  The magnifying Transmitter.
   Note: concept of  Magnifying transmitter was used  by Dr Corum in 2018 to build his Tesla tower  in Milford   
   Texas.
a. In  1899  he  moved  his  research  to  Colorado  Springs preparing plans for Wardenclyffe Tower , in Long Island that was       
     to serve  as  trans Atlantic  communication facility. ( He said  it in 1916 in the interview patent  attorney Drury W.
     Cooper, )

Quote from the interview:
"From my  circuit  you  can  get  either  electromagnetic waves,  90 percent 
of  electromagnetic  waves  if  you  like, and 10 percent in the current energy
that passes through the earth.  Or, you can reverse the process and get 10 percent
of the energy in electromagnetic waves and 90 percent in energy  of  the  current 
that  passes  through  the earth.  .  .  . Note,    for    instance,    the   
mathematical treatise    of Sommerfeld,  who  shows  that  my  theory  is 
correct, that  I was right in my explanations of the phenomena."

4. Two gentleman:  Jonathan Zenneck and Sommerfeld
    Sommerfeld : radiation  from  a  short  vertical  monopole  over  a  finitely conducting  ground.
   this  paper was done based on earlier  created paper  by Jonathan Zenneck that describes a 
    unique  surface  wave  solution  to  Maxwell's  equations. that is in disagreement with
    "electromagnetic space wave studied by Hertz in 1887"
a. so that was   Sommerfeld pointing at  two related concepts of Space Waves consistent with TEM mode  :
    -   "surface waves."
    -"Hertzian waves"
"_{but he used an example the} electrodynamic wave  _{that  is  associated  with  an  electric current flowing along a wire."} (_{old English form of wording used .)}
_______________________________________

James  R.  Wait  pointed at  the fact that ,  according  to  Sommerfeld,  both  the  'space  wave'  and  the 'surface  wave'  components  are  needed,  "in  order  to  satisfy Maxwell's equations and the appropriate boundary conditions,"and that  the  surface  wave  part  is quite  similar to the  Zenneck surface  wave.  concluding that:

surface  wave  part  is quite  similar to the  Zenneck surface  wave

Wait  agrees  that  the  Zenneck surface wave accompanies the space wave,
and can be made to, "predominate under certain . conditions

1.In 1937 Charles  Burrows  conducted  a  series  of  wireless  propagation experiments  at  150  MHz  over  Seneca  Lake  in  upstate     
    New York, using  loaded  vertical  quarter-wave  dipole  antennas.   Burrows concluded   that   the   surface   wave   mode   as modeled
     by Sommerfeld was not excited.   Experiment found, both analytically and experimentally, that it is possible  to use "resonators" to 
     excite a Zenneck wave        that is observed to be 10-20 dB stronger than corresponding radiation fields.
     Note there was also  controversy created by Dr Burrow:
     look here -  https://youtu.be/He5xQOJHlrU?t=78

2.free electron model for the behavior of valence electrons in a conductor is the base  for theoretical model of Zenneck wave .
   _{"it is assumed that valence electrons are assumed to be completely detached from their ions, forming an "electron gas."  due  to  its  low  resistance." - old English form of wording used .}
     The  wave is  supported by  a  planar  or  spherical interface  between  two  homogeneous  media  having  different dielectric constants.
    The Zenneck wave has a phase velocity greater than that of light, and its field strength falls  off  exponentially  at  a  rate  of  e-αd/√d 
     in the  direction  of propagation  along  the  interface,  where  α  is a  frequency-dependent attenuation constant.
    By that we  get to the conclusion that  field intensity of the bound wave is at a maximum at the earth-atmosphere interface and it     
     decays exponentially with height above the surface. the  prediction here is that no cut-off phenomenon is to be encountered.

2.  Practical application:
a. frequency of operation: within the 2.1-kHz wide bandwidth of  2200-meter Amateur Radio band between 135.7-137.8 kHz,
b. the maximum power allowed by FCC on this band is 1W E.R.P
_____________________________________________________________
3. Coil HV 1400 turns gauge AWG 22
a. former for coil: 13.5cm x 86cm
b. primary winding is 8 winds ( turns)
c. diameter  of copper  sphere is around 16cm*
d.  the telescopic mast is made from PVC
____________________________________________________________
*_{suggested  size of the top capacitor( the sphere/ 1/2 of the sphere) is much bigger( the bigger the better)
The minimum distance  between top capacitor and earth ground must be not less than 4 times diameter  of top capacitor.}
