摘要

A double staggered metallic rod array (DSMRA) as the slow wave structure (SWS) is proposed for a terahertz backward wave oscillator (BWO) due to its superior properties. The SWS has a wider region of uniform electric field therefore a sheet beam can be used for effective beam-wave interaction. In this paper Pierce small signal theory is used to analyze the performance of the DSMRA sheet beam BWO operating at 0.2THz. Large signal particle-in-cell simulation predicted the sheet beam BWO could radiate >Guo Liu*,, Wenlong He, Adrian W. Cross, Huabi Yin and David Bowes 110W average output power in the tunable frequency range of 186–227GHz by using a 200mA electron beam.
