Tech-X has released VSim 10.1, the newest version of the VSim computational electromagnetic (EM) software. Built on its powerful Vorpal physics engine, which was designed for the rigorous high performance computing needs of U.S. government research laboratories, VSim 10.1 provides highly accurate analysis, whether running on a laptop or supercomputer. Cross-platform, VSim is flexible and customizable; users can select up to four modules to meet their design needs.
The VSim for Microwave Devices (VSimMD) module is an effective tool for designing, analyzing and optimizing the performance of RF devices, including magnetrons, traveling wave tubes and klystrons. Multipacting, the resonant buildup of secondary electrons, is one of the biggest concerns facing microwave designers working with electron beam devices. When the secondary electron yield is too large, it will trigger an electron avalanche that leads to significant power loss. Designers need to predict this effect; however, not all software products simulate it well. With proprietary algorithms, VSimMD accurately accounts for multipacting, so designers can focus on maximizing power and efficiency. VSimMD comes with an extensive list of example problems, such as multipacting resonances in a waveguide and multipacting growth in a spherical, perfect electric conductor cavity. These examples give users starting points to quickly learn the modeling workflow.
Among the new features in VSim 10.1 are creating rectangular arrays of design geometries enable engineers to quickly test various geometric features on their RF devices and improved particle emitter functionality offers greater control over electron beam simulations. An important addition to VSimMD is the capability to accurately simulate the behavior of particles interacting with transparent materials in microwave devices. With these new features, informative examples and a friendly user interface, VSim 10.1 is a powerful tool. A free, 30 day trial evaluation is available.
