Angle-frequency sensitivity of flat diffraction type devices based on metal-dielectric gratings is investigated in resonant area of wave lengths. The analysis is carried out by the method of waveguide mode for transformation of the linear polarisation wave to the surface wave by diffraction structure. It is shown that similar transformation by structures on the basis of two-level gratings can be effectively realised within (7-9) % frequency range at the fixed propagation angle of primary wave.
