利用电磁场边界条件得到极化波在界面的反射系数和透射系数，并进行数值计算和模拟。模拟结果表明，媒质的电容率与反射系数和透射系数关系密切，当透射媒质的电容率增大时，反射系数和折射系数一般会变小，反之则变大；对斜滑投射，垂直极化波和平行极化波均出现入射波全被反射的情况，且反射波与入射波相位相反。模拟结果还显示，无论是光密媒质还是光疏媒质，平行极化波均出现“无反射”现象，而垂直极化波则没有；垂直极化的反射系数和透射系数曲线是两条平行曲线。

By using the electromagnetic boundary conditions,the reflection coefficiency and transmis-sion coefficiency of the polarized electromagnetic waves were inferred,and their numerical calculations were simulated.Simulation results show that the permittivity of a medium has a close influence on the reflection and transmission coefficiency,when the permittivity of a transmission medium increases,both the two coef-ficiencies generally become smaller,and vice versa.For a ramp projection,the vertically and parallelly polarized waves all have their incident waves totally reflected,but the wave phases of the reflected and the incident are opposite to each other.The simulation results also show the parallelly polarized waves always have “no reflection events”whether it is optically denser medium or thinner medium,and the vertically polarized waves don’t;the curves of the vertically polarized waves;reflection and transmission coefficients are two parallel ones.
