Abstract

The Transmission Line Matrix Method (TLM) is based on a discretization criterion. The paper discusses the limit of relative discretization length (with respect to wavelength) to accurately represent planar structures using the TLM. Convergence of the solution of the TLM with this limit is discussed in an analysis of Frequency Selective Surfaces (FSS) by changing its parameters (shape, dimensions and number of layers). Perfect matching between the TLM and the MoM results is achieved, in addition to the measured results of some fabricated structures.
