Abstract:One of the important issues in electromagnetic applications is the parallel computations of the Specific Absorption Rate (SAR) inside the human head due to radiation from handheld mobile devices antennas. This application has a great demand due to the vast increase in the wireless communications systems everyday. These systems have a hazard effects on the human body. We have introduced the parallel Finite Difference Time Domain (FDTD) algorithm to give a figure of merit about the health hazard effects of wave radiation on the human head. A rectangular microstrip antenna is attached to a human head model in the FDTD parallel code to calculate the Specific Absorption Rate (SAR) inside the human head in very short or almost real time. A parallel processing algorithm is applied on cluster/grid parallel platform of gilda school. The speed up is computed and it is concluded that the parallel algorithm is efficient up to 45 nodes.
