Abstract
The scattering problem is solved for a 3-D Gaussian beam arbitrarily incident upon a two-periodic magnetodielectric layer. New representations are suggested for the scattered field of the 3-D Gaussian beam which allow reducing the computation time required for numerical calculations of the spatial field distribution. Results are presented to illustrate application of the above formulas to calculating the scattered field in the case of oblique incidence of the beam upon the magnetodielectric layer.
KEY WORDS: 3-D Gaussian beam, magnetodielectric layer, quasistatic regime
