The Wireless Power Transmission System


consisting of two concentric conducting spheres separated by a dielectric layer to form a monopole radiator for electrostatic waves.

The patent does not give details how "longitudinal electrostatic or capacitive waves, also called scalar or polarization waves because of their relationship to the Maxwell wave equations" differ in their method of propagation from conventional forms of electromagnetic radiation. It simply states that as the spheres are subject to voltages of opposite polarity the "outer sphere then appears as an ideal monopole radiator to the external dielectric medium, in this case water."[10]

That this design was not effective, according to a report, is due to the configuration of the radiator. The electric field is confined to the region between the two conducting spheres. Little energy, if any, is available to stress the external dielectric medium, the water.

P. Curry's patent for an Underwater Electric Field Communication System, #3,265,972, issued August 9, 1966 proposes a radiator of a different configuration and discusses communications by electrostatic induction. (See Figure 5)



Curry states:

The antenna system for an electromagnetic emission into space circulates energy in accordance with the laws governing electrical current in motion. Since the field strength produced by an antenna is proportional to the alternating currents circulating in it, its optimum structural relationships are directed to a reduction of the total antenna resistance, thus to increase the total current for a given power input to a radiator.[11]

Further on he adds:

While a radiator for electromagnetic emission produces its field strength by the effect of changing currents; the radiator for electrostatic emission of the type here to be described produces its field strength by the effect of changing potentials.[12]

By applying a varying potential to the plates of the radiator, charge of opposite polarity accumulates on the two plates such that a charge gradient exists in the region between the radiators. The patent explains:

... a phase displacement of 90 degrees exists the wave of charge potentials induced by an alternating current signal upon the water ... and the resulting wave of charge displacements occurring in the water body between the segments.[13]

The method of propagation, then, is to cause electrical changes in the two plates resulting in the launching into the medium of sinusoidal carrier waves - as illustrated by the dotted lines in Figure 5.
