Title: Computer Simulation of Human Electromagnetic Waves Interaction
Author: Ali, Idriss Ahmed
Abstract: The topic of this thesis is Computer Simulation of Human Electromagnetic Waves Interaction. The essential task in this thesis was to develop a computational tool to simulate numerically, how the user of hand-held mobile phone is exposed to the electromagnetic fields radiated from the phone. Numerical simulation is important because it is not possible to actually measure the distribution of fields or SAR value (Specific Absorption Rate-the power absorbed by unit mass of the tissue in W/kg) is an important quantity, because the human exposure guidelines are set in terms of SAR. The quantization is done by using differential Maxwell's equations to calculate the electric field intensity and magnetic field intensity. Finite-Difference Time-Domain (FDTD) method is used to calculate the electric field in a human head near a hand-held cellular phone. In the simulation part we consider an imaginary lattice divided into layers of free space and some human tissues. To explain the results clearly, it is advisable to plot them graphically and this was done in chapter six, Results and Discussion.
