| 摘 要： | 为了解多层介质中平面波传播特征,首先借助多层介质中任意介质层内电磁波的场方程以及电磁场的边界条件,推导出多层介质的反射系数和透射系数.然后选取任意相邻3层介质,模拟出各层中电磁波的行波,由此总结出其中电磁波传播特征.最后选取相邻3层介质,分别模拟出四分之一波长匹配层和半波长介质窗,观察到其主要特征.模拟结果能极大地帮助认识多层介质中平面波传播特征,从而更好地对其加以利用.

| Abstract: | To understand the characteristics of plane wave propagation in multilayered media,firstly using the electromagnetic wave field equations in any medium layer,then using boundary conditions to electromagnetic field,the reflection coefficient and transmission coefficient of multilayer medium are deduced.And selecting any of the adjacent 3-layer media,to simulate the travelling electromagnetic wave in each layer,simulation results reveal the characteristics of electromagnetic wave propagation.Finally,selecting the adjacent 3-layer media,to simulate a quarter wavelength matching layer and half wavelength dielectric window,their main features are observed.The results can greatly help to understand the features of plane wave propagation in multi-media,so as to use them better. |
