摘　　要：研究了平行极化波斜入射到理想介质分界面时电场反射系数和透射系数的表达式。根据切向电场、法向电场、总电场幅度等三种情况下反射系数和透射系数的定义方式,给出了其相应的计算表达式,并且其中每一种方式又根据反射波与入射波的切向电场参考方向相同或相反等分成两种情况进行讨论。最后,通过实例证明了三种情况下的电场反射系数和透射系数对于计算反射场和透射场时的等效性。The expressions of reflection and transmission coefficients for parallel polarized waves obliquely incident to ideal medium partition interface are studied.The expressions for the reflection and transmission coefficients are defined in three ways,such as tangential electric field,normal electric field,and total electric field amplitude,and each of them is divided into two cases according to the same or opposite reference phases of the reflected and incident fields.Finally,the equivalence of the reflection and transmission coefficients in the three cases is demonstrated by examples for the calculation of the reflected and transmitted fields.
