Abstract
An electrically small, efficient electromagnetic structure, that may be used as an antenna or waveguide probe, having an electromagnetically closed, velocity-inhibiting conducting path, for supporting a standing, inhibited-velocity wave in response to the flow of an electrical current through the path and a process for establishing the standing wave. Use of the structure is particularly advantageous at the lower end of the electromagnetic spectrum, where various embodiments produce purely vertically polarized radiation in directional and omnidirectional patterns. Various embodiments of the structure include multiple conducting paths and image means to complete the conducting path. Embodiments of the structure may be used to excite the earth-ionosphere cavity at the Schumann resonances.

An electromagnetic antenna including a plurality of closed, interconnected ring elements spaced from each other and transversely disposed on a multiply connected surface.
A process for radiating or receiving electromagnetic energy comprising conducting an electrical current through a path of closed, interconnected conducting ring elements spaced from each other and transversely disposed on a multiply connected surface, and establishing, in response to the flow of said current, an electromagnetic wave along said surface in a condition of resonance.
An electromagnetic antenna including first and second substantially closed, elongated conductors helically disposed on the same multipy connected surface.
A process for radiating or receiving electromagnetic energy comprising conducting first and second electrical currents, respectively, through first and second substantially closed, elongated conductors helically disposed on the same multiply connected surface and establishing, in response to the flow of said currents, an electromagnetic wave along said surface in a condition of resonance.
An electromagnetic antenna comprising a plurality of ring elements, each ring element including a conducting ring element portion and an image means for electromagnetically completing each ring element, said conducting ring element portions being spaced from each other and transversely disposed on the outside surface of an endless tube.
A process for radiating or receiving electromagnetic energy comprising conducting an electrical current through a path of ring elements, each ring element including a conducting ring element portion and an image means for electromagnetically completing each said ring element, said conducting ring element portions being spaced from each other and transversely disposed on the outside surface of an endless tube, and establishing, in response to the flow of said current, an electromagnetic wave along said surface in a condition of resonance.
