Electromagnetic computational method for the scattering of an axisymmetric laser beam by an inhomogeneous body of revolution.
An original computational method for solving the two-dimensional problem of the scattering of an axisymmetric laser beam by an arbitrary-shaped inhomogeneous body of revolution is presented. This method relies on a domain decomposition of the scattering zone into concentric spherical radially homogeneous subdomains and on an expansion of the angular dependence of the fields on the Legendre functions. Numerical results for the fields obtained for various scatterer geometries are presented and analyzed.
