Improvements of MTSS for Simulation of Millimeter and Terahertz Vacuum Electronic Devices

Microwave Tube Simulator Suite (MTSS) is a fully featured tightly integrated software package for microwave tube analysis and design. Recently, some improvements have been made to improve the performance and to make it suitable for simulation of millimeter wave and terahertz vacuum electronic devices. In the paper, the improvements are introduced and a Terahertz folded waveguide traveling wave tube is simulated. The comparison between MTSS and CST PS simulation is performed and the improvements are validated.
