Method of Moment Solution of Surface Integral Equations for Arbitrary 2D Periodic Composite Material Structures

Arbitrary 2D periodic composite material structures, which are excited by plane wave of arbitrary polarization and incoming direction, are analyzed by applying the method of moments (MoM) to surface integral equations (SIEs). Flexibility, efficiency and accuracy is achieved owing to a) Ewald transformation for evaluation of doubly periodic Green's functions, b) general technique to connect material regions through interface of successive cells, and c) higher order basis functions.
