A NOVEL WAVELET-BASED TIME-DOMAIN SIMULATION APPROACH

A novel time domain simulation approach for analyzing three-dimensiona l (3-D) passive microwave structures is presented. The electromagnetic fields of the structure under investigation are expanded into a hiera rchical system of wavelets and scaling functions for all three dimensi ons leading to a stable. multiscale algorithm. By neglecting small wav elet coefficients and thereby reducing the computational effort, this method is equivalent to a finite difference scheme with a time dynamic space adaptive grid, A brief overview of the main ideas and advantage s of the new method as vr ell as the results of two numerical examples are given.
