Scattering from perfectly conducting strips by utilizing an adaptive multiscale moment method – abstract

This paper presents an adaptive multiscale moment method for the analysis of electromagnetic scattering from perfectly conducting two dimensional strips. The advantage of this method is that the number of unknowns can be reduced by setting a threshold as is usually done in wavelet analysis. The novelty of this approach is that the threshold is applied dynamically in an adaptive fashion. It is applied to the unknowns directly by utilizing results of the previous scales and thereby significantly reducing the number of unknowns that is to be solved for. Typical numerical results are presented for some TE and TM cases of electromagnetic scattering from the perfectly conducting strips to illustrate the efficiency of this approach.
