For the generation of millimeter wave from vacuum electron devices, the microfabrication of an interaction circuit is one of the key factors. Two different technologies, a deep etch X-ray lithography (x-ray LIGA) and a deep reactive ion etching (DRIE), were employed for the comparative study and the realization of a backward-wave oscillator. Both methods showed accurate and reliable results, which...
An asymmetric magnet system was designed for 0.1 THz BWO devices due to the asymmetry introduced by coupling waveguide. This magnet system confines the electron beam of 12 kV and 50 mA and maintains its radius, 0.18 mm, along the circuit length.
