Planar V-band slow-wave structures for low-voltage tubes with sheet electron beam

Abstract

Planar slow-wave structures (SWS) on dielectric substrates at V-band (50-70 GHz) are studied. The SWS circuits are designed and fabricated. Basic electromagnetic parameters of the SWS are calculated. We consider the meander and interdigital SWSs, which are designed for operation in O-type traveling-wave tube amplifier and backward-wave oscillator, respectively.
