Estimation and simulation of SAR distribution in biological objects excited by various types of electromagnetic signals

Abstract

This article presents estimation and simulation results of the distribution of specific absorption rate (SAR) by biological objects, which are tissues of the human body (blood, muscles, fat). TEM-cell was used as a source of excitation. The simulation was carried out using various types of excitation (Gaussian pulse, bipolar Gaussian pulse and amplitude-modulated sinusoid). It is revealed that different signals cause differences in the distribution of SAR in the biological objects under consideration.
