Parallel 2D large-signal modeling of cascaded TWT amplifiers

摘要

Travelling Wave Tubes (TWTs) based on serpentine or folded waveguide slow-wave structures are promising devices for operation in mm and sub-mm wavelength ranges. As a result of our recent search for the new devices, capable to produce higher power together with a broad bandwidth, there was done a wide study on a multiple-beam cascaded travelling-wave tube concept
