Fast analysis of 3-D doubly periodic structures with complex geometry and anisotropic materials using the adaptive integral method

Full-wave modeling of 3-D doubly periodic structures with non-orthogonal lattices is an important topic area in computational electromagnetics due to its wide range of possible applications; most notably, frequency selective surfaces (FSS) and metamaterials. The hybrid finite element boundary integral (FEBI) method has been used to analyze the "artificial puck plate" FSS using a triangular grid composed of isotropic media.
