CST Studio Suite® is a high-performance 3D EM analysis software package for designing,

analyzing and optimizing electromagnetic (EM) components and systems.

Electromagnetic field simulation software

Electromagnetic field solvers for applications across the EM spectrum are contained within a single user interface in CST Studio Suite. The solvers can be coupled to perform hybrid simulations, giving engineers the flexibility to analyze whole systems made up of multiple components in an efficient and straightforward way. Co-design with other SIMULIA products allows EM simulation to be integrated into the design flow and drives the development process from the earliest stages.


CST Studio Suite® gives customers access to multiple electromagnetic (EM) simulation solvers which use methods such as the finite element method (FEM) the finite integration technique (FIT), and the transmission line matrix method (TLM). These represent the most powerful general purpose solvers for high frequency simulation tasks.


The excellent workflow integration available within CST Studio Suite® provides reliable data exchange options which help to reduce the design engineer’s workload.CST Studio Suite is renowned for its superb CAD and EDA data import capabilities. The sophisticated healing mechanisms, which restore the integrity of flawed or non-compliant data, are particularly important as even one corrupted element can prevent the use of the whole part.


With System Assembly and Modeling (SAM), CST Studio Suite® provides an environment that simplifies the management of simulation projects, enabling the intuitive construction of electromagnetic (EM) systems and straightforward management of complex simulation flows using schematic modeling.

Antenna Magus

Antenna Magus is a software tool for accelerating the antenna design and modeling process. It features validated antenna models that can be exported into CST Studio Suite® from a huge antenna database with over 350 antennas.
