The electromagnetic simulation software CST STUDIO SUITE ™ is the culmination of many years of research and development into the most efficient and accurate computational solutions to electromagnetic design. It comprises the following modules:

- CST DESIGN ENVIRONMENT™ (CST DE) is the access point to the CST STUDIO SUITE™
- CST MICROWAVE STUDIO® (CST MWS) is a specialist tool for the fast and accurate 3D EM simulation of high frequency problems. Along with a broad application range, CST MICROWAVE STUDIO® offers considerable product to market advantages: Shorter development cycles - Virtual prototyping before physical trials - Optimization instead of experimentation.
- CST DESIGN STUDIO™ (CST DS) provides a powerful design environment in which the results from diverse simulators can be combined and analyzed.
- CST EM STUDIO™ (CST EMS) is an easy-to-use tool for the analysis and design of static and low frequency structures. - CST PARTICLE STUDIO™ (CST PS) for simulation of free moving charged particles as in electron guns, cathode ray tubes,...
