Abstract: A surface wave launcher surrounds and provides structure complimentary to an antenna and converts (transforms) a near field produced by the antenna into a cylindrical surface wave structure with a strong electric or magnetic field component parallel to a launching interface and propagating two-dimensionally from the launcher. The surface wave launcher leverages the interface found along ocean-air or ground-air to increase a field strength transmitted for a given antenna size and power available. The surface wave launcher maintains a relatively small structure compared to wavelength offering mobility to a very low frequency transmitter. Due to localization of the surface wave energy near the interface, communications using the surface wave retain a desirable low probability of detection.
