Accurate computation of wide-band response of electromganetic scattering problems via Maehly approximation

The best uniform rational approximation, performed by the Maehly approximation, is applied to the method of moments (MOM) to obtain the radar cross section (RCS) over a broad frequency band. Numerical results for three dimensional arbitrarily shaped perfectly electrically conducting (PEC) bodies are considered. Compared with the asymptotic waveform evaluation (AWE) technique, the presented technique is found to be efficient in much broader frequency band with lower memory required. © 2007 Wiley Periodicals, Inc.
