Combined Exposure Ratio Evaluation for Micro-Power Devices

Abstract

The exposure ratio of multiple micro-power devices is difficult to evaluate in terms of the choices of measure point and public exposure control limit due to various frequencies, antenna transmit powers, and device topologies; whereas the traditional multi-device evaluation method was found unable to achieve consistent and rational results. In order to address these challenges, a combined radiation device mode is introduced to simplify the choice of measure point, and a convert algorithm is proposed to determine public exposure control limit in any distance. The adjusting factors are added to the convert algorithm to improve its position consistency and limit rationality, and a neural network is designed to optimize its nonlinear coefficients. Finally, the radiation pressure tests in lineal and rectangular topologies are provided to corroborate our studies.
