介绍一种精确计算多层平面介质波导归一化正交辐射模的方法.在全辐射模的情况下,为了保证模的正交性,给出了准奇模和准偶模的确定方法.这些方法适用于计算机编程,为模传播法的建立和实际应用奠定了基础.本文最后给出几个应用的实例.

We present in this paper an exact method of determining the orthonormal radiation modes of multilayer planar dielectric waveguides. To assure the orthogonality,a simple method is also developed to determine the quasi-odd and quasi-even modes in the full radiation case. These methods are suitable for computer programming, and will serve as basic consideration for further development of the Mode Propagation Method (MPM ).
