N2 - 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\ \Omega with the potential to enhance the efficiency of energy exchange process between the electron beam and high frequency field in terahertz TWT.
