BISTATIC SCATTERING WIDTH COMPUTATION FOR NONLINEAR ISOTROPIC INFINITE MULTILAYER CIRCULAR-CYLINDERS

An iterative approach to the approximate computation of the bistatic s cattering width (BSW) for nonlinear multilayer concentric circular cyl inders is proposed. The nonlinear layers are assumed to exhibit a Kerr -like nonlinearity. The approach is based on the distorted-wave Born a pproximation, and the initial linear solution is obtained by using the recursive Richmond formulas. A TM illumination is considered Numerica l results are reported concerning weakly nonlinear shells and concentr ic cylinders coated with nonlinear layers, or presenting nonlinear die lectric nuclei.
