The Influence of Shape of the Body on SAR Coefficient in the Biological Object

摘要

The paper presents results of SAR (Specific Absorption Rate) calculations in different spheroid biological objects. The aim of the study was to trace the influence of body geometry on the value of the whole-body SAR. The biological model that has been taken into account is a prolate spheroid. The spheroid is an isotropic lossy dielectric. The mass of the bodies were taken was constant. The external medium was assumed to be free space and the excitation as a uniform plane wave. The calculations were carried out for two cases of polarization. The simulations were done at 900 MHz and 1800 MHz frequency. The values of the SAR were calculated based on the calculating of the electric field strength distribution inside the body using semi-analytical method.
