Abstract :
A fast and accurate code for calculation of eigenwaves in single- and double-vane slow-wave structures (SWS) is developed. Such SWS are used in sheet-beam traveling wave tubes (TWTs) and backward-wave oscillators (BWOs) at sub-THz and THz frequencies. Results of numerical modeling of SWS for a G-band sheet-beam TWT are presented.
