The dispersion characteristics of hemispherical resonators with a plane mirror covered with a periodic structure of the "comb" type and low-Q open systems consisting of a radiating antenna of the "horn" type and a plane mirror with a periodic structure are investigated experimentally. Effective interaction between an electron beam close to the periodic structure with the harmonics (up to the tenth) of the diffraction mode and also with higher harmonics in the traveling-wave modes are found.
