Paper Abstract

A new type of metamaterial is proposed that may be considered as frequency selective surface (FSS), consisting of printed metal patches on inhomogeneous, periodic substrates. To analyze these structures a system of equations obtained from the Rigorous Coupled Wave Analysis (RCWA) is solved by the Method of Moments (MoM) with sub-domain rooftop basis functions and Galerkin testing functions. Several examples are outlined and analyzed using the MoM/RCWA technique. In order to validate the procedure, comparisons with a commercial time domain solver are performed. The introduced structures are designed using a micro-genetic algorithm in order to achieve artificial magnetic conductors (AMC) with optimum performance.
