Abstract :
Dosimetry model of the human brain based on the surface integral equation (SIE) is developed. Mathematical model of a lossy homogeneous biological tissue is derived from the equivalence theorem and using the appropriate boundary conditions. Numerical solution of the SIE has been carried out using the method of moments. Numerical results for the calculated electric and magnetic fields induced at the surface of the human brain are presented for the case of the plane wave exposure at frequency 900 MHz and 1800 MHz, respectively. In addition, comparison of the peak and average SAR values are given.
