Abstract

This paper has performed a simulation study involving several different tubes, nonuniform and uniform, using the 2.5V electromagnetic particle-in-cell code TWOQUICK to elucidate the the process occurring in the NBWO, and to ascertain the possible advantage of using nonuniform amplitude slow wave structure over one that is uniform. Results showed that the slow phase velocity surface wave that interacts with the electron beam coexists with an ordinary waveguide mode (fast TM wave), which forms a standing wave in both nonuniform and uniform BWO.
