Abstract :
Broadband high-gain traveling wave tube (TWT) amplifiers are widely employed in communications and other related applications. For design of such devices, numerical modeling and optimization tools are of great importance. In this paper, we describe a new 2.5D code for simulation of a helix TWT.
