High Performance Grid Computation of the Scattered Field Formulation for N Order Debye Modeling of the General Dispersive Media

With the advent of the current wireless communication revolution and the increase in its applications, the electromagnetic researchers in conjunction with the medical physicians take the initiative of studying the price of this beneficial technical revolution. It is the health hazards due to the electromagnetic radiation on the human body. The most cost efficient mean of studying these effects is the numerical simulation using the popular FDTD numerical technique. The FDTD simulates the existence of the human body tissues using many fitting models. One of the most famous one is the Debye model. In this paper, the Nth-order Debye model for modelling the human tissues is represented using the scattered field formulation for deducing the FDTD update equation. The scattered field formulation is an accurate method of implementing the different excitation mechanisms for the waves that impinging on the human dispersive tissues media. Although the FDTD is an efficient method, it is a heavy computational one. It may take time of several hours or even days to simulate a single run of a specific problem. In this paper, a parallel scheme is utilized to speed up the running time of the 3D FDTD that includes The Nth-order Debye model. The parallel computations are running on VO (Virtual organization) of the EUMED grid platform. The speed up and behaviour over different number of processors is monitored.
