In this paper, the temperature rise in the user's head due to different mobile phone models is computed for a realistic usage pattern, where the Pennes Bioheat Equation is solved using a conformal Finite-Difference Time-Domain (FDTD)-based electromagnetic solver, SEMCAD X. A heterogeneous High Resolution European Female Head (HR-EFH) with twenty five different tissues is used to simulate the human head, whereas four semi-realistic CAD models, i.e., candy-bar with external antenna, candy-bar with internal antenna, clamshell with external antenna, and clamshell with internal antenna, operating at 900 MHz with antenna output power of 600 mW are used to simulate the commercially available mobile phone models. The results show different temperature rise values in the user's head due to the different mobile phone handset models.
