Process of difractional dispersion of the slow waves field in a cylindrical dielectric waveguide (the weak relativistic electron beam emitator )by the coaxial open periodic structures(OPS)was experimentally investigated in the frequencies region of 37 GHz - 66 GHz. It was found out that the OPS resonance properties have place in the frequencies region connected with the birth of -2d and -3d radiated space harmonics. These properties are defined by the OPS geometrical dimensions and are characterized by an ai normal increase of the difractional fields (far and short distances) amplitude. A sharp increase of the connection of the electron beam with the OPS field, and radiation of a big quantity HF - energy,which is taken away from electron beam, were both observed.These results can be a basis for creation of the millimeter waves range powerful amplifiers and oscillators.
