Several recent studies investigated the impact of mobile phone radiation on cells of the human body. Thermal effects have been investigated, via experimentation or simulation in many types of research. This paper deals with thermal effects of electromagnetic radiation, produced from a mobile phone with a frequency of 1.8 GHz, in human dura tissue, using the finite-difference-time- domain method (FDTD). This study focuses on the thermal effect response of a semi-infinite biological tissue. Maxwell’s equations and transient bioheat transfer equation were numerically calculated, to predict the effects on the transient temperature of dura tissue. Electric and magnetic field simulation is also done. The prediction of the temperature evolution in biological bodies can be used effectively for thermal diagnostics in medical practices. Modeling the electromagnetic field distribution in the human body allows providing a good answer to the worried persons. This analysis and results can be used during the design process for the newest mobile phones, and also help in determining the biological effects due to exposure to electromagnetic waves irradiated from the mobile phone.
Key words: Finite-difference-time-domain method, mobile phone radiation, thermal effect, dura tissue.
