Electromagnetic Coupling between a Conducting Body and an Aperture in an Infinite Conducting Plane.
Abstract
In this work, the problem of electromagnetic coupling between a conducting body and an aperture in an infinite conducting plane of zero thickness is considered. The method of moments is utilized to obtain a matrix formulation for the equivalent magnetic current in the aperture and the electric current on the conducting body. The general solution is then applied to problems for which the conducting body is a wire. The aperture is arbitrarily sized and shaped. The wire is of finite length (with or without loads) or of infinite length. Triangular patching is used to model the aperture. Local position vectors are chosen as the expansion functions in the aperture. Pulse functions are used as expansion functions for the current on the wire in the vicinity of the aperture, and two exponential wave functions are used as expansion functions for the transmission line mode on the wire. A Galerkin solution is used. Power transmitted through the aperture is evaluated. In addition, an equivalent circuit of the aperture for the transmission line mode on the loaded wire is derived. The numerical results show very good agreement with other available data. (Author)
