Abstract :
Modifications to the popular Rao-Wilton-Glisson (RWG) triangle subdomain basis functions are described that allow their use in analyzing periodic structures where the electric or magnetic surface current must be allowed to flow across unit cell boundaries. Examples of frequency selective surfaces with this requirement include strip grids and meanderline polarizers.
