小波变换法求解单脉冲在低损耗媒质中的传播
Solving the propagation and reflection of mono pulse in the layered inhomogeneous and low lossy media with wavelet transform method
【摘要】 文章提出了一种利用小波变换求解分层、非均匀、低损耗媒质中波的传播与反射问题的新方法。它解决了 Fourier变换法及线性化近似方法无法处理的问题。并用该方法计算一特例与已有数值方法的计算结果进行比较 ,结果基本一致。
【Abstract】 In this paper, a wavelet transform method is presented to solve the propagation and reflection of mono pulse in the layered inhomogeneous and low lossy media. It can solve the problem which can not be solved with Fourier transform method and linear approximation method. Using the method, a special example is analyzed. The results obtained are compared with the ones solved with numerical method. The two solutions are the same.
