Abstract: This article reviews some of the research carried out by our group on modeling of metamaterials whose building blocks are not very tightly coupled. To solve the problems involving complex metamaterials, which may either be periodic with slowly convergent behaviors or large non-periodic arrays, we apply the Characteristics Basis Function Method (CBFM) which is a powerful paradigm for handling such large complex problems. The problems are formulated by using integral equations and the Method of Moments (MoM) in conjunction with the Characteristic Basis Function Method (CBFM) to significantly reduce the number of unknowns. We apply the technique to solve problems involving different plasmonic metamaterials including periodic nanorods, finite random arrays of rods as well as a structure which has a general loop geometry building block
