2D modeling of TWTs based on serpentine and folded waveguide structures
Summary form only given. Travelling Wave Tubes (TWTs) with slow-wave structures, based on a serpentine or folded waveguides, are promising devices for operation at sub-Terahertz and Terahertz frequency ranges. Development of such types of TWTs requires accurate and efficient computational tools suitable for their design, analysis and optimization. Recently we have developed the new model1, which allows us to extend an existed 2D large-signal code TESLA-CC2 on the modeling of amplifiers based on serpentine or folded waveguide structures.
