The Wi-tap one wire system is the physical representation of a one wire with ground return circuit, the same as built by Konstantine Meyl and a few other recent Tesla wireless system experimenters. The transmitter and the receiver are coupled together by electric current energy flowing through the wire. The circuit is completed by an equivalent electric current flowing through the conducting ground plane below them.
In operation, the electrical energy produced by the transmitter passes by conduction as an electric current through the wire to the receiver. Electrical energy also passes between the transmitter and the receiver as an electric current through the ground plane upon which the transmission-reception demonstration system is positioned.
The ground plane around both the transmitter and the receiver comprise a portion of the single conducting ground plane upon which the entire system is positioned. The transmitter’s elevated terminal is capacitively coupled to its immediately surrounding portion of the ground plane, and the receiver’s elevated terminal is capacitively coupled to its immediately surrounding portion of the ground plane. The portion of the ground plane in the vicinity of the transmitter provides an electrical termination point for the electric field produced by its elevated terminal electrode.>
There is a space between the transmitter’s elevated terminal and the ground plane below it, which is small when compared to the space between the terminal and the distant receiver. Because of this, the electric field energy cannot travel through the space between the two widely-separated elevated terminals. Instead, the electric field energy is transformed into conduction currents that flow through the conducting ground plane.
This explains why there is no significant correlation between transmitter-receiver separation and system throughput. This also helps to explain the reduction in efficiency that is observed when the interconnecting wire is replaced with a wide conducting ribbon. If you were to assemble the entire apparatus on a long wooden table set up in the upper-story loft of an all-wood three story building, the influence of the terrestrial ground plane would be reduced and your results would be different. — G Peterson, 11 Nov. 2015
The transmitter and the receiver are connected together with a wire. The entire apparatus is positioned over a ground plane. The wire is a conductor; the ground plane below is a conductor, only there is a small space between the raised terminals and the conducting ground plane that is insulating. If you set up differences of potential on the transmitter’s raised terminal, you create around it corresponding fluctuations of potential. But, since the distance from the raised terminal to the conducting ground plane is small, as compared with the distance of the receiver, the energy cannot travel through the space between the two raised terminals and get there, but is immediately transformed into conduction currents, and these currents travel through the conducting ground plane like currents over a wire with a return. The energy is recovered in the receiving circuit, not by a beam that passes between the two raised terminals, but it travels by conduction and is recovered in this way. — G. Peterson, 25 Feb. 2012.
This is a one wire with ground return circuit. Current passes through the wire between the Tesla coil transmitter and receiver. The circuit is completed by current through the earth. The conducting ground plane around the transmitter and the receiver both comprise a portion of the larger conducting ground plane upon which the “one-wire with ground return” demo system is positioned. Electrostatic induction or displacement current capacitively couples the transmitter’s elevated terminal to its local ground and the receiver’s elevated terminal to its local ground. The conducting ground plane in the vicinity of the transmitter provides an electrical termination point for the locally produced electric field that reduces the electric energy coupled into the single conductor transmission line wave or TM wave traveling along the wire between the two resonators. This effect is compounded as the separation between transmitter and receiver increases leading to complete suppression of the TM wave. — G. Peterson, 03 Oct. 2011
A nearby conductor other than the line itself may provide a termination point and thereby reduce energy coupled into the TM wave. This has relevance to Tesla’s 1891-1893 table-top demonstrations. — G. Peterson 06 Oct. 2011
