A class of physical optics-SVD derived basis functions for solving electromagnetic scattering problems

A novel procedure is presented for solving electromagnetic scattering problems in a computationally efficient and numerically rigorous manner. It is based on the use of universal bases which are obtained by applying the SVD procedure to physical optics derived basis functions. These bases, which are constructed completely avoiding any MoM-type approach, can be used for any angle of incidence and lead to a matrix whose dimensions are relatively small. Moreover, it can be shown that the matrix dimensions are weakly dependent upon the size of the scatterer
