Scattering of a three- dimensional Gaussian beam with circular cross section from a gyrotropic slab

The problem of the scattering of a 3-D Gaussian beam incident at an arbitrary angle onto a gyrotropic slab is formulated and solved. New formulas for the scattered 3-D beam fields in the form of the single integrals are derived. They allow to reduce the time spent on the calculations of the scattered beam fields. Numerical results are presented.
