On the numerical computation of shielded microstrip structures
Abstract
In this paper solutions of the homogeneous wave equation are considered for planar structures of arbitrary contour surrounded by a conducting cylindrical shield. For configurations such as this, the problem can be reduced to an integral eigenvalue equation governing the surface current density Js on the planar structure independent of the special geometry. This can be solved in general form by the application of Galerkin's method since it is possible to specify suitable orthogonal expansion functions for the current density Js. Computation of shielded stripline dispersion and the resonance frequencies of shielded circular disks and rings serves as a numerical example and as a basis for the discussion of the relative convergence phenomenon which the method exhibits.
