摘　　要：介绍了时域有限差分法(FDTD)方法的原理,并基于该方法,研究了电磁波在多层媒质中的反射与透射情况.通过实例证明,FDTD法能够模拟波的自然传播情况,因此在处理多层复杂媒质的反射与透射问题,以及显示全空间的场强分布方面,有其巨大的优势.This paper introduces the principle of finite difference time domain （FDTD） method, and studies the reflection and transmission of electronic waves in multi-layer medium based on this method. Some cases are used to demonstrate that FDTD is able to simulate the natural process of wave transmission, and that this method is remarkably efficient in handling problems associated with reflection and transmission of multi-layer complicated mediums and in displaying distribution of electric field of the whole space.
