New micromachining techniques now provide the opportunity to fabricate vacuum electron devices with dimensions suitable for operation in the terahertz region of the electromagnetic spectrum. In this paper, results of theoretical and numerical simulation studies of a MW-class, large diameter terahertz backward wave oscillator are presented. A novel full electromagnetic particle-in-cell simulation tool UNIPIC is also introduced. With this method, we studied the device at the frequency of 0.14 THz. It is found that the steady-state, single-frequency operation in this oversized situation could be realized by the property of surface wave near the upper cutoff area.
