Abstract:

Future radar and military communication systems need powerful signal generators with much higher frequencies. In this paper, results of the theoretical and numerical simulation studies of a MW-class, large diameter terahertz wave generator are presented. The device consists of a miniaturized foilless diode as well as an oversized rectangular slow wave structure (SWS) which could support surface wave and provide a strong beam-wave coupling. With the method of Particle-in-cell simulation, we investigated the operating characteristics of a prototype 0.22 THz signal generator. It is found that the steady-state, single-mode operation in overmoded situation could be realized by the property of surface wave, and its operation in the first Brillion region demonstrates that the device performs as a forward wave oscillator, which would be employed in military applications.
