FEM-ABC and MFCM Techniques Applied to the Solution of 2D Scattering Problems

چکیده
The problem of solving open 2D scattering problems using the finite element method (FEM) and the multi-filament current method (MFCM) is addressed in this paper. The second order absorbing boundary condition of Bayliss-Turkel, for noncircular boundaries, and the filament positioning problem in MFCM are investigated. Two problems defined by two perfect cylindric dielectric bodies, with circular and square cross section, illuminated by a transverse magnetic plane wave are studied. Both the procedures investigated to place the filaments are efficient. The results obtained using the FEM, with first and second order triangular elements, are compared to those obtained using MFCM and show good agreement.

متن کاملEffective Preconditioners for the Solution of Hybrid FEM/MoM Matrix Equations using Combined Formulations
Hybrid FEM/MoM modeling codes generate large systems of equations that are generally solved using inward-looking, outward-looking or combined formulations. For many types of problems, the combined formulation is preferred because it does not require a direct inversion of the coefficient matrices and can be solved using iterative solution techniques. An effective preconditioner is a crucial part...
