本文件规定了因射频（RF）电磁场（EMF）发射设备而入射到人体头部或身体的功率密度（PD）保守且可重复计算的计算程序。描述的计算程序是时域有限差分法（FDTD）和有限元法（FEM），这两种计算技术可用于通过求解Maxwella？在指定的计算不确定性内的s方程。此处规定的程序适用于大多数人群在使用手持式和佩戴式射频发射设备期间的暴露评估。这些方法适用于具有单个或多个发射器或天线的设备，并且可以使用其辐射部分或多个部分在距离人类头部或身体200 mm的距离处操作。 本文件可用于确定靠近头部和身体使用的不同类型射频发射设备是否符合任何适用的最大局部放电要求，包括与其他射频发射或非发射设备或附件（如皮带夹）结合使用的设备，或嵌入衣服中的设备。这些协议和程序的总体适用频率范围为6 GHz至300 GHz。本文件涵盖的射频发射设备类别包括但不限于移动电话、个人电脑中的无线电发射器、台式机和笔记本电脑设备以及多频带和多天线设备。本文件的程序不适用于由拟植入体内的装置或物体发射或改变的电磁场的局部放电评估。

This document specifies computational procedures for conservative and reproducible computations of power density (PD) incident to a human head or body due to radiofrequency (RF) electromagnetic field (EMF) transmitting devices. The computational procedures described are finite-difference time-domain (FDTD) and finite element methods (FEM), which are computational techniques that can be used to determine electromagnetic quantities by solving Maxwell's equations within a specified computational uncertainty. The procedures specified here apply to exposure evaluations for a significant majority of the population during the use of hand-held and body-worn RF transmitting devices. The methods apply to devices that can feature single or multiple transmitters or antennas, and that can be operated with their radiating part or parts at distances up to 200 mm from a human head or body. This document can be employed to determine conformity with any applicable maximum PD requirements of different types of RF transmitting devices used in close proximity to the head and body, including those combined with other RF transmitting or non-transmitting devices or accessories (e.g. belt-clip), or embedded in garments. The overall applicable frequency range of these protocols and procedures is from 6 GHz to 300 GHz. The RF transmitting device categories covered in this document include but are not limited to mobile telephones, radio transmitters in personal computers, desktop and laptop devices, and multi-band and multi-antenna devices. The procedures of this document do not apply to PD evaluation of electromagnetic fields emitted or altered by devices or objects intended to be implanted in the body.
