The input impedance and antenna characteristics of a cavity-backed plasma covered ground plane antenna

A description of two methods which are based on a cavity Green's function technique and a waveguide Green's technique which can be used to calculate the input impedance, electromagnetic fields, antenna probe currents, and antenna characteristics of a cavity-backed plasma covered ground plane antenna is presented. A description of the formulation of the theory behind the methods is given. Comparison of theory and experiment are made.
