摘要

小波理论正成为表征电磁结构的一个非常有用的工具，因为小波族具有精确表示函数和算子的优良性质。目前，小波理论已成功地应用于矩量法求解电磁积分方程。然而，在本文中，矩形波导的模态行为的计算采用Nystrom方法，这是一个优雅和简单的方法来求解积分方程。为了提高效率，采用类小波基对未知电流进行扩展。因此，内存需求和计算成本显著降低。

Efficient waveguide mode computation using wavelet-like basis functions

Wavelet theory is becoming a very useful tool to characterize electromagnetic structures due to the excellent properties of wavelet families for the accurate representation of functions and operators. Up to now, wavelet theory has been applied successfully to electromagnetic integral equations solved through moment methods. However, in this paper, the computation of the modal behavior of rectangular waveguides strongly perturbed by axial cylindrical conducting objects is taken via the Nystrom method, which is an elegant and simple procedure for solving integral equations. In order to improve the efficiency, wavelet-like bases are used to expand the unknown electric current. Therefore, memory requirements and computational costs are reduced dramatically.
