介绍了时域有限差分法 ( F DTD)的基本原理 ;模拟了电磁波在大地非均匀介质信道中的传播 ,研究了透地通信系统中的电磁波在有耗大地分层面的反射和透射 ,得出了对透地通信系统设计有重要意义的反射系数和透射系数 ,说明了
The principle of the Finite Difference Time Domain(FDTD) method id introduced, the propagation characteristic of EM wave in the inhomogeneous and multiplayer channel of communication system through the earth is calculated and simulated, and the reflection and transmission coefficients are obtained based on the different electric parameters in the channel The result is very important to design the system of communication through the earth it has shown that the FDTD method is a very effective way to solve the transmission problem in complex mediums
