The mathematical model of electromagnetic field distribution in human head phantom from external source

The rapid development and deployment of mobile communications focused the scientists attention on electromagnetic field distribution problem. Numerical techniques, such as finite element method integral equations method, finite difference time domain method( FDTD) and some hybrid methods have been taken into account. These approaches allow to obtain a good accuracy in the estimation of the electromagnetic (EM) field distribution in the given phantom. FDTD method required to evaluate six components of EM field and the time discretization, what demanded the powerful computer and long time to compute. The attempt to increase the accuracy of computation by increasing of cells number collided with convergence problem. To avoid this problem the integral equations method was chosen for research. The results of modeling confirmed the correctness and adequacy of proposed model for evaluation of electromagnetic field distribution from mobile phone in human head phantom.
