It is shown that dispersion curves describing a spectrum of Trivelpiece-Gould (TG) waves in periodic plasma-filled waveguides have a fractal nature. They are not solid lines as for other types of waves in periodic waveguides but suffer from discontinuities of the first kind at any , where P and Q are integers, d means period of the corrugation, and m transverse index of a mode. The width of gaps, which correspond to forbidden bands, decreases with both increasing integer P and decreasing depth of corrugations. The evaluation of the Hausdorf dimension of the dispersion curves is presented. It is shown that it does not depend on the transverse index of a TG mode. Finally, qualitative consequences of the fractal nature of TG waves for plasma microwave electronics are discussed. The fiel d distribution of plasma waves is substantially distorted near forbidden bands forming regions with a high density of energy where the density of energy can exceed its overage value more then by the order. This effect is provided by contribution of the highest spatial harmonics. Product Description popup.authors popup.nrat_date 2020-04-02 Close
