SAR simulation

The telecommunications sector is making great advances aimed at delivering an even stream of high tech devices, covering the significant consumer demands in this sector. EM simulation is increasingly becoming an indispensable tool in the design flow, not only on the antenna level but also on the phone and environmental levels. This article compares simulated results with measurements for several steps in the phone design chain. Read full article..

Transmitters used in vehicle environments present potential threats to the health and safety of vehicle users, in terms of both human exposure to electromagnetic fields and vehicle EMC (electromagnetic compatibility). The recently revised automotive EMC directive (2004/104/EC) now requires vehicle manufacturers to identify acceptable frequencies, powers and antenna installations that can be used on vehicles without compromising their EMC performance. The simulations presented here were performed with CST MICROSTRIPES™. Read full article..

Human head models like the SAM phantom are already regularly used to test the influence on mobile phone performance as well as to check the compliance to SAR standards. However, the hand also influences the field distribution significantly. The following article shows the CST MICROWAVE STUDIO® (CST MWS) simulation results of a complete Sony Ericsson mobile phone in relation to head and hand phantoms. Read full article..

A standardized spherical phantom head such as the one described in this example is commonly used for SAR investigations and measurements. Read full article..
