Progress in Theoretical Design and Numerical Simulation of High Power Terahertz Backward Wave Oscillator
Results of theoretical analysis and numerical simulation studies of a MW-class, overmoded terahertz oscillator are presented. The device consists of a large diameter crosssection, slow wave structure with a unique profile of wall radius specifically designed to support surface wave and to provide a strong beam-wave coupling at a moderate voltage. Under the condition of 500 kV voltage and 2 kA beam current, the 2.5-D particle-in-cell simulation predicted the output power of 41MW at the frequency of 0.143 THz. And an efficiency of 4.1% was also obtained with a perfect time plot and fine spectrum characteristic.
