介绍了一种非均介质中电场响应的数值模拟方法.传输线模型法是以惠更斯原理为基础,通过建立麦克斯韦方程中电场和磁场与传输线方程中电压和电流的等效关系,按时间步进的办法来模拟电磁场响应的一种电磁场数值计算方法.从一维介质中电场传播的物理过程出发,导出了点电流源情形下地质介质中电场响应迭代方程;编程计算了非均匀介质中的电场响应,其结果表明,用这种方法对非均匀介质中的电场响应进行数值模拟是行之有效的.

Introduce a numerical method for calculating the response of electric in heterogeneous medium. Transmission Line method （TLM） is based on Huygen＇s law, constructed an equivalent relation between electric and magnetic field in Maxwell equation and voltage and current in transmission line equation, finally, simulated the response of electromagnetic field by time-step. From transmission line method, educed the iteration of electromagnetic response equation with point electrical source and programmed to calculating the response of electric in heterogeneous medium. Results indicated that it is effective using Transmission Line method to simulation the response of electric in heterogeneous medium.
