Surface Waves in Oversized G-Band Slow-Wave Structures with Rectangular Corrugations

Abstract: Surface waves in oversized G-band slow-wave structure with rectangularly corrugated wall are analyzed numerically. The inner corrugation generates cylindrical surface wave. The outer corrugation also generates transverse magnetic surface wave. The upper cut-offs of surface waves are controlled by corrugation amplitude. In excitation of the surface waves by an annular electron beam, the slow cyclotron interaction as well as the Cherenkov interaction occur due to there-dimensional beam perturbations. The slow cy… Show more

“…The value of the magnetic field can be changed from zero to approximately 1 T; the field is 0.82 T in this study. The microwave output is picked up by rectangular horn antennas of F-and G-bands, which are EIA standard rectangular waveguides with cutoff frequencies of 74 and 116 GHz [15], respectively, located typically 600 mm away from the output window. After providing an adequate amount of attenuation, the output powers are detected by crystal detectors.…”

“…In this case, the distance between beam and corrugation surface is estimated as about 4 mm and all the radiations disappear. To excite the higher order modes as well as the surface wave, the beam should propagate within the interaction region of the oversized BWO [8].…”

“…The radius of SWS is about 30 mm to match the beam radius used in our experiments. We determine the corrugation parameters based on numerical analysis of the dispersion curves and the beam interactions presented in [7], [8]. The SWS parameters of K-and G-band BWO are listed in Table 1.…”
