A generalized network formulation for a circular aperture in conducting plane

Abstract

The electric field integro-differential equations for electromagnetic scattering from a perfectly conducting plane perforated by a circular aperture is solved by the method of moments. The problem is formulated as an operator equation, where the unknown is the equivalent magnetic current over the aperture and the known is the tangential magnetic field over the aperture region for the complete conducting plane i.e, aperture shorted. Finally, a matrix method of solution is described and a numerical solution is obtained. Several numerical results are shown for illustration.
