Characteristic Modes for a Slot in a Conducting Plane.
Abstract
In this report, the theory of characteristic modes for slots is used to solve the problem of an infinitely long slot in a conducting plane in an unbounded medium illuminated by either a transverse electric or a transverse magnetic uniform plane wave. The characteristic currents are defined as the eigenfunctions of a certain generalized eigenvalue equation involving the admittance operator and its real part. The theory is general, applicable to wide as well as narrow slots, and gives a modal expansion of all quantities and parameters of interest usually encountered in electromagnetic compatibility problems. This modal expansion converges rapidly when the slot is narrow. The characteristic currents and fields, the equivalent magnetic current, and the radiation pattern are computed for different slot widths. Analytic expressions for the special case of a narrow slot are also given. Key words: Aperture admittance; Characteristic modes; Electromagnetic transmission; Slot in a plane; Two dimensional slot.
