This document provides guidance on the definition of the incident power density in correlation with surface temperature elevation in the frequency range from 6 GHz to 300 GHz. Using numerical simulations or measurement, this guide is also applicable to compliance assessment of wireless products operating in millimeter wave frequencies. The incident power density (IPD) is generally spatially averaged over an averaging area. Two quantities may be used to define the spatially averaged IPD, either using the normal component of IPD vectors crossing the surface, or magnitude of IPD vectors (norm) averaged over an area independent of the orientation. This document provides guidance for determining the appropriate definition of IPD. The guide examines theoretical, computational, and measurement data that are relevant to the validity of each method, taking into account the dependence of the IPD metric and its averaging methods on surface temperature rise in the frequency range 6 GHz to 300 GHz. This guide might be used in the development of standards for the EMF exposure limits or in the EMF compliance assessment standards. New IEEE Standard - Active.
