Abstract:
As one type of full-metal slow wave structure (SWS), the staggered double-vane (SDV) used in traveling wave tube (TWT) has many advantages. In this paper, a new microstructure SWS using the staggered double-vane is put forward by using two adjacent modes, which can work in the 340 GHz TWT with ultra-high broad bandwidth. The dispersion characteristics, interaction impedance and the simple input/output taper coupler for TWT are calculated and analyzed. The simulation result shows that this kind of SDV-SWS has a wide bandwidth of 78 GHz. And the high interaction impedance can be achieved to 0.5 Ω with the potential to enhance the efficiency of energy exchange process between the electron beam and high frequency field in terahertz TWT.
