MOMTD/FDTD混合法分析线天线与近场媒质的相互作用

A Hybrid MOMTD/FDTD Approach for Studying of Interaction of Wire Antenna with Dielectrics

采用能够充分发挥MOM与FDTD法各自优势的MOMTD/FDTD混合法,对任意形状线天线与近场媒质的相互作用在时域进行仿真计算。在对MOMTD/FDTD混合法进行验证的基础上,用MOMTD/(FD)2TD混合方法对脉冲电压激励下的线天线与由色散媒质构成的人体头部之间的相互作用进行了仿真研究,计算出了头部的局部比吸收能量分布。

MOMTD/FDTD hybrid method is the technique that combines FDTD and MOMTD. The hybrid method is applicable to complex geometries comprising thin wires and arbitrary inhomogeneous dielectric structures in time domain. Numerical results that validate the hybrid method are presented. MOMTD/（FD） 2TD hybrid method is employed to simulate the interaction of pulse fed wire antenna with human head . Spatial distribution of Local Specific Absorption in human head is calculated.
