Abstract
The diffraction problem of the plane inhomogeneous H-polarized wave, generated by the modulated electronic beam on a periodic reflecting grating, is solved using the decomposition method. The grooves of this grating are filled with metamaterial with a negative dielectric permeability and frequency dispersion. The resonance radiation effect of electromagnetic waves is found by such structure and the conditions of its occurrences are definite.
KEY WORDS: negative permittivity, electron beam, diffraction grating, metamaterial, frequency dispersion, resonance radiation
