Assessment of Polarization Dependence of Body Shadow Effect on Dosimetry Measurementsin 2.4 GHz Band

Abstract

Ubiquitous wireless connectivity has undergone a major transformation in recent years in different sectors of daily life, with a broad and diverse application scope. The number of personal devices operating in the frequency band of 2.4 GHz has especially grown with the use of smart phones, tablets, and laptops equipped with Wi-Fi interfaces. Despite the recognized benefits of this useful form of communication, there are serious concerns about how to ensure safe exposure conditions to electromagnetic fields (EMF), given that compliance tests require an accurate knowledge of elusive influence factors in order to obtain reliable conclusions about exposure conditions. This work focuses particularly on the analysis of the influence of polarization on the level of intensity of the BSE; for this purpose, the BSE is quantified when the incident wave is horizontally polarized following the same protocol used in previous work to compare the results of both polarizations.
