IEC/IEEE 62704-1:20 17(E)定义了当用于确定暴露于具有已知不确定性的无线通信设备的人体中的峰值空间平均比吸收率(SAR)时，时域有限差分(FDTD)技术的应用方法。它定义了验证被测器件（DUT）数值模型的方法，并在SAR模拟中使用时评估其不确定性。此外，它定义了确定立方体积中峰值空间平均SAR和验证FDTD模拟软件正确实现的程序。适用频率范围为30 MHz至6 GHz。 本文件不推荐具体的SAR限值，因为这些限值可以在其他地方找到，例如在国际非电离辐射防护委员会（ICNIRP）发布的指南[1]或IEEE Std C95.1[3]中找到。 关键词:空间平均比吸收率，时域有限差分，人体

IEC/IEEE 62704-1:2017(E) defines the methodology for the application of the finite-difference time domain (FDTD) technique when used for determining the peak spatial-average specific absorption rate (SAR) in the human body exposed to wireless communication devices with known uncertainty. It defines methods to validate the numerical model of the device under test (DUT) and to assess its uncertainty when used in SAR simulations. Moreover, it defines procedures to determine the peak spatial-average SAR in a cubical volume and to validate the correct implementation of the FDTD simulation software. The applicable frequency range is 30 MHz to 6 GHz.
This document does not recommend specific SAR limits since these are found elsewhere, for example, in the guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) [1] or in IEEE Std C95.1 [3].
