CST – Computer Simulation Technology
3D EMC/EMI Simulation of Automotive Multimedia Systems
July 2011
A key challenge in automotive product design is the compliance to electromagnetic compatibility (EMC) and interference (EMI) requirements in a cost-driven project environment. Traditionally, EMC and EMI issues are solved in the EMC lab, often without getting a full understanding of the underlying effects. The adoption of 3D field simulation provides an insight into the root causes of electromagnetic resonance effects occurring in the product, enabling fast design cycles and high product quality.

Modeling and Measurement of Shielding Enclosures
The shielding effectiveness (SE) of an enclosure has been simulated by using CST MICROWAVE STUDIO® (CST MWS) and then compared to measurement from a known reference case. Despite the fact that the shielded enclosure was simulated neglecting many details,...
