A GENERALIZED METHOD FOR TWO DIMENSIONAL SCATTERING PROBLEMS UNDER TE INCIDENCE WITH THE USE OF SPECTRAL TECHNIQUES

A new method for characreming electrically large scatteren and solring the scattering of multiple objects in two dimensions for TE polarization of the incldent field is presented. Large objects are dicided into smaller ones. The method of moments and spectral techniques are used to compute a transference mahir for each single subscatferer, which relates the incident and scattered jie1d.x Then, with the use of an iteratir,e method for soliing the interaction between all of them, the response for the whole system is obtained. This procedure is more efficient rhan the method of moments when applied to the scatterer considered as a single element. 0 1996 John Wilqv & Sons, Inc.
