摘要

We study the moment method (MM) to deal with Harr wavelet basis due to the problem of electromagnetic scattering from the fractal rough surface. The vanishing moment properties and the capability of the wavelets to adjust themselves to the fractalsurface lead to a sparse impedance matrix and faster computation. Compared to the measured data and the conventional MM, the result shows that the wavelet basis functions provide substantial reductions in both memory requirements and computation time.
