Abstract :
In this communication, the Scale Changing Technique is used for the global electromagnetic simulation of frequency selective surfaces consisting of non-uniform rectangular waveguides perforating a thick metallic plate. Excellent agreement between the Scale Changing Technique and the Finite Element Method is observed with substantial reduction in computation time and memory when using the proposed technique, which may be compatible with an optimization process.
