Reduction of vector unknowns using geometric symmetry in a triangular-patch moment method for electromagnetic scattering and radiation analysis

A simplification method for the boundary element model developed by H. Tsuboi et al. (1990) is applied to the triangular-patch moment method in order to reduce the number of vector unknowns. The simplification of the computational model is performed by a variable transformation using the spatial eig...

Description
Summary:A simplification method for the boundary element model developed by H. Tsuboi et al. (1990) is applied to the triangular-patch moment method in order to reduce the number of vector unknowns. The simplification of the computational model is performed by a variable transformation using the spatial eigenmodes, which is similar to transformation used in the boundary element case. However, the unknown vectors have to be arranged according to the geometry of the rotational symmetry because of the varying directions of the unknown vectors. The applicability of the simplification method was verified by a flat square plate model and a TEM (transverse electromagnetic) cell model.< >
