Abstract :
Teraphysics Corp. is currently developing two novel, 650 GHz backward wave oscillators (BWOs). The computations of BWO output power have depended on the classic literature for a round electron beam in a helical structure [1, 2]. This may not be directly applicable to these novel devices. Therefore, we have computed the performance of biplanar interdigital, and helical BWOs using the 3D particle-in-cell (PIC) code, MAFIA. The results indicate MAFIA simulations are in fairly good agreement with the classic approximations.
