On sar evaluation in the model of human head subjected to radio-frequency electromagnetic field

The paper aims at finding the analytical formula for Specific Absorption Rate (SAR), the coefficient which determines the thermal effect oil the biological tissue while subjected to the electromagnetic radiation. The thermal effect is especially important when, the radio-frequency electromagnetic field is considered. At recent time, many publications, concerning this matter, have been launched in the world but the problem is still far from being completed. The analytical solution may help in mastering the fast procedures which can evaluate SAR in particular case or in testing numerical models.
