Method of Moments and T-Matrix Hybrid

Hybrid computational schemes combining the advantages of a method moments formulation field integral equation and T-matrix are developed in this article. The hybrid methods particularly efficient when describing interaction electrically small complex objects large canonical shapes such as spherical multilayered bodies where is reduced to Mie series making an interesting alternative design implantable antennas or exposure evaluations. Method performance tested on multilayer model human head. Along with method, evaluation transition matrix arbitrarily shaped object presented characteristic mode decomposition performed, exhibiting fourfold numerical precision compared conventional approaches.
