An analytical series solution is derived within the Rayleigh hypothesis to compute the efficiencies of a crossed grating illuminated by an arbitrary polarized beam. A comparison with previously reported numerical results for a dielectric crossed grating illuminated by a plane wave shows good agreement. The formulas given can be directly implemented on a personal computer.
