CST MICROWAVE STUDIO® (CST MWS) is the leading edge tool for the fast and accurate simulation of high frequency (HF) devices such as antennas, filters, couplers, planar and multi-layer structures and SI and EMC effects. CST MWS offers considerable product to market advantages such as shorter development cycles, virtual prototyping before physical trials, and optimization instead of experimentation. Besides the flagship time domain simulator using proprietary PERFECT BOUNDARY APPROXIMATION (PBA)® technology, CST MWS offers frequency domain on hexahedral and tetrahedral meshes, an Integral Equation solver for large structures, and a fast s-parameter solver dedicated to highly resonant structures. Features include robust optimization, co-simulation with best-in-class tools and powerful scripting capabilities. Filters for the import of specific CAD files and the extraction of SPICE parameters enhance design possibilities and save time. CST MICROWAVE STUDIO® is seen by an increasing number of engineers as the industry standard development tool. More information at http://www.cst.com/Content/Products/MWS/Overview.aspx
