论文摘要

本文开发了结合了场积分方程和t-matrix方法的方法的优势的混合计算方案。当描述电较小的复杂物体和典型形状的电气大物体(例如球形多层体)的相互作用时,混合方法特别有效,其中将T-Matrix方法简化为MIE系列,从而使该方法成为植入天线或暴露天线或暴露评估的指定中有趣的选择。方法性能在人头的球形多层模型上进行了测试。除了混合方法外,还提出了对任意形状对象的过渡矩阵的评估,并执行特征模式分解,与常规方法相比,具有四倍的数值精度。

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