ELECTROMAGNETIC SCATTERING BY NONLINEAR DIELECTRIC CYLINDERS WITH NON-KERR-LIKE NONLINEARITIES

In this letter, electromagnetic scattering by nonlinear dielectric cyl inders under transverse magnetic illumination is considered. The nonli nearity is assumed to be so weak as to allow the application of an ite rative approach based on the distorted-wave Born approximation. The bi static and back-scattering radar cross sections per unit length are co mputed. The key feature of the Letter is the use of nonlinearities rep resented by models different from previously assumed Kerr-like ones. I n particular, we consider nonlinearities that are of the saturated and are characterized by power laws. (C) 1995 John Wiley & Sons, Inc.
