Abstract :
A two-dimensional solver using a coupled finite element method (FEM)/boundary element method (BEM) for solving general electromagnetic scattering from chiral objects is formulated. The bymoment method (BMM) uses a set of FEM solutions to approximate the fields in and around the scatterer, and a coefficient expansion method to couple the set of FEM solutions with the BEM. The basic BMM theory is expanded to include possible chiral characteristics of materials. Validation is performed by comparing numerical results to analytically obtained results.<>
