摘要

研究电磁波在有耗介质中的瞬态传播特性对地球物理勘探具有重要意义。研究了基于有限元模拟软件COMSOL multi-physics计算电磁波在层状介质中瞬态传播特性的方法，分析了吸收边界条件和数值稳定性条件。建立了两层介质模型，对平面波传播特性进行了数值模拟。研究发现，对电磁波在多层介质中传播的时间波动特性进行分析，可以提供边界位置的指示。

Computing the plane electromagnetic wave transient propagation in lossy medium based on COMSOL

It was very important for geophysical exploration to study the electromagnetic wave transient propagation characteristic in the lossy medium. A method for computing the electromagnetic wave transient propagation characteristic in layered medium based on the finite element simulation software COMSOL multi-physics was studied and the absorbing boundary condition and numerical stability condition were analyzed. The two layer medium model was set up and the numerical modeling of the plane wave propagating characteristic was conducted. It was found that the temporal fluctuation characteristic analysis of electromagnetic wave propagation in multilayer medium might provides an indication of the boundary position.
