| Abstract: | 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. |
