| 摘 要： | 提出了一种利用小波变换求解不连续性变系数电磁波动方程高频解的新方法，解决了 Ｆｏｕｒｉｅｒ 变换法无法解决的分层非均匀无耗媒质中波的传播与反射问题。并用该方法计算了一个 Ｆｏｕｒｉｅｒ 变换法能求解的特例，两种方法计算结果完全一致

| Abstract: | Here we present a new continuous wavelet transform method to solve the high-frequency solution of electromagnetic wave equations of varying coefficients with discontinuities in an infinite domain. The method can solve non-uniform medium which can not be solved with Fourier method. Using the method, we analyzed a special example which can be solved with Fourier method. The two solutions are the same. |
