Abstract:The extended aggregate basis function method (EABFM) is proposed to analyze the electromagnetic scattering by the composite structure with periodic array. The generation of the impedance matrix in the EABFM is still time consuming. The fast dipole method (FDM) and the equivalent dipole‐moment method (EDM) are applied to accelerate the fill‐in of the matrix. Several numerical examples are performed. Simulation results validate the accuracy and efficiency of the proposed method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
