Abstract

We describe a formulation for the diffraction of a plane wave normally incident on a square array of perfectly conducting cylinders of specified length. This is a particular case of a thick capacitive grid, for which no previous rigorous model exists. The formulation is based on a modal description of the fields between the cylinders, and methods are specified for the determination of the three types of mode (TE, TM and TEM). Numerical tests on the formulation and examples of its results are presented.
