The paper presents a numerical electromagnetic simulations of SAR limited to human tissues based on FDTD algorithm using Sim4Life platform. Flat-bottomed dielectric vessel (flat phantom) and half-wave symmetric dipole antenna were modeled. Simulations were done for the frequencies 0.9 GHz and 0.6 GHz. The analysis were performed according to the IEEE/IEC62704-1 standard and include distributions of electric and magnetic fields around the phantom and antenna. Finally, SAR distributions in the phantom and near the antenna.

W pracy przedstawiono numeryczne symulacje elektromagnetyczne SAR dla tkanek ludzkich w oparciu o algorytm FDTD z wykorzystaniem platformy Sim4Life. Zamodelowano płaskodenny dielektryk (fantom płaski) oraz półfalową symetryczną antenę dipolową. Symulacje wykonano dla częstotliwości 0.9 GHz i 0.6 GHz. Analizy zostały wykonane zgodnie ze standardem IEEE/IEC62704-1 i obejmują rozkłady pól elektrycznych i magnetycznych wokół fantomu i anteny. Na koniec zaprezentowano rozkłady SAR w fantomie i pobliżu anteny.
