A Well Conditioned Formulation for the Analysis of Multi-Layered Frequency Selective Surfaces Using a Cascaded Matrix Approach
Abstract
A general method to analyse mult-layered Frequency Selective Surfaces is given which includes a full coupling of evanescent and decaying modes in a well conditioned manner. The method is capable of analysing arbitrary lossy dielectric and magnetic materials used as supports with partially conducting (Salisbury) surfaces and is valid for incident plane waves with arbitrary polarisation and angles of incidence. The solution is obtained by modal matching of the fields in the apertures of each surface in a manner which satisfies the boundary conditions using Galerkin testing. One important feature is the manner in which the cascaded matrices are put together to avoid numerical problems. Theoretical predictions have been made on a wide range of surfaces and tested against experiments with satisfactory results. Great Britain.
