Electromagnetic Simulation Software

Simulation and Analysis of Electromagnetic Fields

Electromagnetic simulation software enables engineers to investigate the electromagnetic properties of components or whole systems efficiently. Electromagnetic (EM) systems often pose multiscale challenges, such as very wide frequency ranges and electrically large structures with very fine detail. Dedicated solvers exploit specific numerical technologies for fast and accurate simulation. EM simulation can be applied throughout the entire design process. From the inception of an idea, to the synthesis of components to meet specifications, to analyzing the electromagnetic performance under operational conditions: virtual prototypes are transforming the design cycle.

EM simulation software is a game changer when it comes to reducing the time and cost of bringing a product to market, not just in the high-tech industries of electronics and communication, but also in aerospace, defense, transportation and life sciences. Analysis with EM software ranges from individual components such as antennas, sensors and chips up to entire devices, including aircraft, smartphones and MRI.

Co-design within the SIMULIA product portfolio integrates EM simulation into industry processes, accelerating the process of evaluating the performance, reliability and safety of materials and products before committing to physical prototypes. Multiphysics design flows on the 3DEXPERIENCE platform drive the development process from the earliest stages.

Bioelectromagnetics (BioEM)

BioEM is the study of how fields propagate through and interact with the human body. BioEM is relevant to the design of medical systems such as MRI and implanted devices, but also to the analysis of communication devices and other systems that expose the human to EM fields.

Electromagnetic Compatibility Applications

By including EMC compliant design at an early stage, additional costly development iterations can be avoided later on. Simulation using CST Studio Suite technology allows problems to be identified and corrected from the start of the design process before the first prototype is even built.

Electromagnetic Compatibility simulation


With the high data rates, compact structure and complex layout of modern circuit boards and packages, maintaining signal integrity (SI), power integrity (PI) and electromagnetic compatibility (EMC) can be difficult. CST Studio Suite technology can help engineers design, analyze and improve PCB layouts.

Particle Dynamics

CST Studio Suite technology can be used for designing charged particle devices, ranging from microwave devices such as magnetrons and electron tubes to components for particle accelerators.
