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.

Electrical Fast Transient/Burst (EFT/B) Susceptibility of an LV Circuit Breaker
The coupled voltage at component level has been simulated using CST MICROWAVE STUDIO SUITE® for two PCB releases of the same Low Voltage Circuit Breaker (LV-CB) electronic control scheme. The results show a good agreement with actual measurements.

Cavity Modes in a Shielding Enclosure
The effectiveness of shielding enclosures is reduced by apertures for heat dissipation, cable penetrations, etc. The EMI from a slot in a shielding enclosure is calculated by a finite-difference time-domain method and by CST MICROWAVE STUDIO®, with excellent...

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,...

Shielding Analysis of a Metallic Enclosure
The aim of this article is to emphasize the application of a statistical approach to the analysis of the shielding properties of a real enclosure for radio communication equipment. A model of the enclosure was simulated with the CST MICROWAVE STUDIO®...
