Abstract

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.
