SAR Determination for Indoor, Far Field Exposure

Electromagnetic compatibility (field recently extended with bio-electromagnetic compatibility) is a never-ending challenge for any type of radio-frequency non-ionizing radiation. Human behavior in this ubiquitous field is anytime a topic of constant interest. Evaluation of short or long term impact of electromagnetic non-ionizing radiation on humans should be priority. We here share a case study focused on the estimation of specific absorption rate (SAR). The electromagnetic source has been considered as far-field communication system, while the 3D human model has been previously presented and tested by the authors. The evaluation of human exposure is performed by determining the SAR values on the surface of the 3D human body model placed inside an office room, in various exposure scenarios. The SAR values have been determined by simulations using a specialized software program, SIMULIA CST Suite Studio, the Microwave Module of the software. The obtained SAR values have been compared with the limits imposed by standards in force.
