Abstract: A large increase in the signal strength of the surface wave transmitted from a buried or sub-surface antenna is achieved by shaping the interface region, at which the sub-surface wave is directed, into a cylindrical or spherical lens.

Abstract: A triggerable spark-gap is provided wherein the main gap discharge time is controlled by placing an auxiliary pair of discharge electrodes inside one of the main gap electrodes and causing a discharge for emitting ultra-violet light. The ultraviolet light illuminates the region in which the main discharge channel will form through a small aperture in the one of the main electrodes within which the auxiliary pair of electrodes are placed.
