Internal and near-surface electromagnetic fields for a uniaxial anisotropic cylinder illuminated with a Gaussian beam

Abstract

Within the generalized Lorenz-Mie theory (GLMT) framework, an analytical solution to the scattering by a uniaxial anisotropic cylinder, for oblique incidence of an on-axis Gaussian beam, is constructed by expanding the incident Gaussian beam, scattered fields as well as internal fields in terms of appropriate cylindrical vector wave functions (CVWFs). The unknown expansion coefficients are determined by virtue of the boundary conditions. For a localized beam model, numerical results are provided for the normalized internal and near-surface field intensity distributions, and the scattering characteristics are discussed concisely.
