Abstract:

In this paper the results of investigations of the electrodynamic properties of a two-barrel four-gap W-band resonator are presented. It is shown that in the considered resonator it is possible to achieve a multiple ratio of the frequency f27 = 99.61 GHz of the higher mode to the frequency of the main mode f1 = 33.22 GHz (i.e., f27/f1 = 3). Calculation of the field distribution showed that both modes with frequency f1 and f27 can interact simultaneously with the beam. A study was made of the possibility of reducing the nonuniformity of the distribution of the longitudinal component of the electric field between the passage channels by using lateral cavities, which are short-circuited segments of a rectangular waveguide, shunting the gap. The mode at which the multiplicity of 3 (f27/f1 = 3) is achieved, can be used to create frequency multipliers and thereby gain amplification in the W-band of wavelengths.
