| Abstract: | A novel and especially concise slow wave structure, called sine waveguide, is proposed to produce and amplify the millimeter wave and terahertz wave. It has some unique properties, including low ohmic loss, and low reflection aside from easy fabrication. In this paper, the high frequency characteristics are calculated, and particle-in-cell simulation analyses are carried out for a 220 GHz traveling wave tube amplifier and a 220 GHz backward wave oscillator. The investigation results show that the sine waveguide would be a promising slow-wave structure for high power millimeter wave and terahertz wave radiation sources. |
