Simulation of cold magnetized plasmas with the 3D electromagnetic software CST Microwave StudioÂ® The strong agreement between cold-test parameters simulated with MWS and those measured experimentally demonstrates the potential of this code to reduce the time and cost of TWT development. The results were compared to experimental data, as well as to results from MAFIA, another three-dimensional simulation code from CST currently used at the NASA Glenn Research Center (GRC). The electromagnetic field simulation software package CST MICROWAVE STUDIO (MWS) was used to compute the cold-test parameters - frequency-phase dispersion, on-axis impedance, and attenuation - for a traveling-wave tube (TWT) slow-wave circuit. Three-Dimensional Simulation of Traveling-Wave Tube Cold-Test Characteristics Using CST MICROWAVE STUDIOĬhevalier, Christine T. The application of Microwave Studio to TWT cold-test circuit optimization is described. The optimization procedure allows simultaneous optimization of circuit specifications including on-axis interaction impedance, bandwidth or geometric limitations. The internal optimizer of CST MICROWAVE STUDIO (MWS) was used along with an application-specific Visual Basic for Applications (VBA) script to develop a method to optimize traveling-wave tube (TWT) cold-test circuit performance. The described approach can be applied to other members of the CST STUDIO product line as well.ĬST MWS is one component of the CST STUDIO SUITE™ package, which includes CST DESIGN ENVIRONMENT™, CST DESIGN STUDIO™, CST EM STUDIO™, and CST PARTICLE STUDIO™.Traveling-Wave Tube Cold-Test Circuit Optimization Using CST MICROWAVE STUDIOĬhevalier, Christine T. COM and ActiveX interfaces allow behind the scenes data transfer and tight integration between the two programs.

This interface allows CST MWS users to take advantage of the extensive data manipulation, signal processing, and graphics capability in MATLAB. The product offers users shorter development cycles through virtual prototyping before physical trials and optimization instead of experimentation.ĬST MICROWAVE STUDIO provides a link between MATLAB ® and CST MWS's VBA macro language.

CST MWS specializes in providing fast and accurate 3D electromagnetic simulation of high frequency problems. CST MICROWAVE STUDIO ® (CST MWS) is the culmination of many years of research and development into the most efficient and accurate computational solutions to 3D electromagnetic designs.
