Research on Channel Characteristics of Through-the-Earth Communication Based on FDTD Method

Abstract

The channel characteristic of through-the-earth communication is calculated and simulated by Finite Difference Time Domain (FDTD) method. The reflection and transmission coefficients are obtained based on the different electric parameters in the channel. And the propagating characteristics of the layered earth in a loop antenna are investigated. The result can be served as a helpful guideline to design the through-the-earth communication system. It has shown that the FDTD method is a very effective way to solve the transmission problem in complex mediums.
