Computer programs for electromagnetic coupling between a conducting body and an aperture in an infinite conducting plane

Computer programs for the analysis of electromagnetic coupling between a thin straight conducting wire and an aperture in an infinite conducting plane are briefly described and listed in this report. The aperture is of arbitrary shape and size. The wire is of finite length (with or without loads) or of infinite length. The excitation is either a plane wave incident from the opposite side of the wire or TEM voltages applied on the wire. The current distributions in the aperture and on the wire are computed. In addition, for the case of TEM voltage excitation, the power transmitted through the aperture is computed. For the case of plane wave excitation, this document evaluates an equivalent circuit of the aperture for the transmission line mode on an infinitely long wire or an arbitrarily loaded wire.
