Efficient Modeling of Composite Material Structures Based on CPU/GPU parallelized Symmetrical MoM/SIE Matrix Solution

摘要

The general purpose code for electromagnetic modeling of composite metallic and dielectric structures, which is based on Higher Order Basis Functions (HOBFs) with Galerkin testing of Electric Field Integral Equation (EFIE) for metallic structures and the PMCHW formulation for dielectric/magnetic boundary surfaces, is adjusted for construction of symmetrical MoM matrices. The out-of-core direct solver for symmetrical matrices based on CPU/GPU parallelized Cholesky algorithm is developed. Efficiency of symmetrical EFIE/PMCHW formulation in conjunction with CPU/GPU parallelized out-of-core solver is demonstrated on example of Luneburg lens antenna of 30 λ in diameter, which is solved at desktop PC.
