A numerical dosimetry procedure is applied to a biological tissue in order to evaluate the temperature increase produced by RF exposure. The originality of the proposed method regards the application of the bio-heat equation in a vascularized region considering a discrete blood vessel structure which operates as a cooling system in the biological region. First, the blood structure is assumed to be...
A 3D numerical study is proposed to compute the specific absorption rate (SAR) and maximum temperature increase in the human eye exposed to RF fields generated by handheld transmitters. A very accurate model of the human eye is proposed using a very fine discretization with 0.25 mm cubic cells that permits to consider many eye tissues in the calculations. The numerical aspects of the bioheat equation...
A numerical study is proposed to investigate the effects of different RF sources on the specific absorption rate (SAR) and maximum temperature increase in the human eye at different frequencies. In particular, a new model of the human head is presented and compared with an anatomical model of the visible human. The high resolution (0.5 mm) of the proposed model allows to consider more eye tissues...
