SAR-Human Head Exposed to Mobile Phone

With common use of modern communication devices, it has become an imperative to calculate the impact of EM fields to human body. This application focuses to the effects of a mobile phone to human head at 1.8 GHz.

By using the WIPL-D MoM efficiency, it is possible to simulate realistic model of the cell phone and the human head. The geometries were provided as CAD files, imported, repaired and meshed in WIPL-D Pro CAD with all the details originating in the mechanical CAD model. The cell radiates via PIFA and exposes the human phantom to EM radiation, which is demonstrated via both near field and SAR. Results also include radiation pattern for 3 scenarios (PIFE in free space, mounted to cell and in vicinity of head).

All simulations are carried out at regular desktop quad core PC. For electrically more complicated models, the simulation time has been decreased by using WIPL-D GPU solver and widely available inexpensive Nvidia CPU cards. The GTX series offers large computing power for rather small investment. The end result is that simulation time are measured in seconds or minutes at most.
