High-speed SAR prediction for mass production stages in a factory by H-field measurements [cellular radio applications]

The purpose of this study is to develop a new system with which SAR measurements can be made in a shorter period of time, suitable for mass production stages. Our major concern is to evaluate the specific absorption rate (SAR) from the viewpoint of quality control in a factory, but not the compliance testing or regulation. For factory use, we have developed a new measurement system that makes use of a noble algorithm that predicts the SAR from the measurement of the magnetic field distribution in the vicinity of a cellular radio in free space. The developed system can predict the SAR in as little as 30 seconds, and is thus particularly suitable for the production stage in a factory for quality control purposes.
