Abstract :
In this paper, as an extension of the iterative MoM/SBR (shooting and bouncing ray), the FEM/MoM is combined with high-frequency asymptotic techniques(HFAT) along with the iterative algorithm. As a result, the equivalent currents can be evaluated with higher accuracy by taking into account the presence of a large structure. The outline of the formulation and validation in both two- and three-dimensional structures, specifically in the application of reflector antenna systems, are presented.
