ABSTRAKT

Scattering of a 3-D Gaussian beam incident at a small angle onto a double-periodic magnetodielectric slab has been formulated and solved. The new formulas for incident and scattered 3-D Gaussian beam fields have been derived in the form of single integrals. These allow reducing the time spent upon numerical calculations of the incident and scattered beam fields and improving their accuracy. The calculations of the 3-D Gaussian beam obliquely incident onto magnetodielectric slab with the derived formulas are illustrated.
