Latest Progress in Dosimetry and Near-Field Evaluations for Mobile Communications Devices

the necessity of accurate dosimetric and especially of general near-field evaluations in wireless product development and certification will continuously grow in the coming years. In product development, far-field evaluations provide insufficient information for analyzing and optimizing the performance of transmitters operating in complex environments. Driven by growing public concern, new and more strict legal requirements regarding compliance with safety limits might be released in the near future which will demand enhanced and more precise dosimetric tools and procedures in order to minimize any unnecessary restrictions for the exploration of wireless technology. In addition, special fools will be required to analyze, develop, optimize, and verify exposure systems for bioexperiments addressing public health risk concern. the objective of this paper is to review the latest progress in near-field measurement technology and to discuss future needs.
