Abstract
- We present a room electromagnetics-based theory which primarily models the diffuse multipath components (DMC) power density with a simple circuit model, and afterwards includes the line-of-sight (LOS) component to predict the total exposure in a realistic environment. Given a human absorption cross section (ACS) and its location from a transmitter (Tx), the average whole-body specific absorption rate (\SARwb) can be determined by the proposed circuit model for ultra-wideband (UWB) and wireless local area network (WLAN) systems. The \SARwb in humans in a realistic office environment for both UWB and WLAN systems is investigated as part of application. The theory is simulated with the Advanced Design System (ADS) software, and excellent agreement between theoretical and simulated values are obtained in terms of relative errors (<2%). The model may be very useful for \SARwb prediction in realistic complex indoor environments. [ABSTRACT FROM PUBLISHER]
