Abstract—Temperature increase analysis has been performed with consideration to the anatomical model of the human head exposed to a cellular phone operating at 900 MHz. Four different numerical methods, in particular an implicit method based on the Alternating Direction Implicit technique (ADI), were applied to solve the Bio-Heat Equation (BHE), their advantages and limitations were compared using a canonical case. The tests performed on the latest have shown that the implicit approach is well adapted to solve this type of equations. The rise of temperature in the human head exposed to the RF emission of a mobile phone with a radiated power of 250 mW at 900 MHz was analyzed. In addition the influence of the presence of the telephone kit close to the head was discussed. The influence of different thermal parameters such as the thermal conductivity and the blood perfusion coefficient on the rise of temperature has been analyzed.
