Comparison of SAR in human body radiated from mobile phone and tablet computer

Recently, wireless radio terminals such as mobile phones and tablet computers are increasing and developing rapidly. The effects of the electromagnetic (EM) waves in the human body from the wireless radio terminal have been paid attention. Therefore, we have calculated the specific absorption rate (SAR) in human tissues radiated from simple EM source models as like dipole antennas. In this paper, we constructed high-resolution numerical model of the flip phone and tablet computer. In addition, we compared the SARs in human body from the flip phone and the tablet computer using the finite-difference time-domain (FDTD) method. As the results, we found the SARs by the flip phone are higher than those by the tablet computer. All calculated SARs are below the safety guideline for RF energy exposure set up by the International Commission Non-Ionizing Radiation Protection (ICNIRP).
