An exact analytical solution to the transmission of a Gaussian beam through a gyrotropic cylinder is formulated in terms of a cylindrical vector wave function expansion form. By applying the continuous boundary conditions of electromagnetic fields, the unknown expansion coefficients of the scattered and internal fields are determined. For a localized beam model, numerical results are presented for the normalized near-surface and internal field intensity distributions, and the propagation characteristics are discussed concisely.
