Abstract To determine a correction model that can be used to correct the measured specific absorption rate (SAR) in a homogeneous phantom when its dielectric properties deviates from standardized target values. The correction model is established based on the method of electromagnetic numerical simulation. The method is verified by comparison with the data in the IEC 62209＼IEEE 1528 standards at 835MHz. Based on the method, correction models at 3.5 and 28GHz, which are the candidate bands for the future communication systems, are proposed. Employing the correction models reduces the SAR measurement uncertainty, thereby improving the reproducibility of SAR compliance assessment between laboratories. Another benefit is that it enables the use of broadband tissue-equivalent liquids, whose dielectric parameters are not currently within the tight tolerances of existing standards. The use of broadband liquids reduces the cost of SAR measurement.

Key words： electromagnetic radiation SAR mobile communication tissue-equivalent liquid;electromagnetic numerical simulation;revised model of SAR
