Surface Wave Radiation from a Thick, Semi-Infinite Plane with a Reactive Surface

The idealized surface wave radiator considered here is a thick, semi-infinite plane with a reactive surface. The scattered field is found when symmetrical and unsymmetrical surface waves are radiated at the termination of the plane. Since there are semi-infinite boundary conditions, the Wiener-Hopf technique is used for finding equations describing the scattered field. These equations contain a series of unknown constants which require numerical solution. Field patterns are plotted for different plane thicknesses and surface reactances with even excitation. The scattering of a plane wave by a thick, reactive plane is also discussed briefly.
