Abstract

This paper presents a simulation of a three-stage cascaded staggered double vane slow-wave structure (SWS). The results suggest that >10 W of peak power can be produced between 208 GHz and 238 GHz and a maximum gain of 32.4 dB at 220 GHz, driven by three 20 mA electron beams. The proposed circuit does not require an attenuator and the length of each stage is 27.45 mm. Because of the current density and short circuit length, the structure shows application potential as a terahertz radiation source.

Keywords
