Abstract :
A 1-THz backward wave oscillator was designed and simulated. The introduction of the double corrugation rectangular waveguide SWS permits an effective interaction with cylindrical electron beams. The advantages of the backward wave operation permit remarkable performance up to 6 mW output power, in compact and realizable way, with a beam current density compatible with carbon nanotube cold cathode.
