Abstract :

In this article, the biological effects of high-frequency electromagnetic waves on the body are first investigated. Then the amount of specific absorption rate (SAR) and the factors affecting it are investigated and then the amount of SAR is simulated in the standard model IEC-66209 in which the head tissue and a reference antenna called Diple are modeled and the effect of changing physical parameters onSAR, such as tissue conductivity, tilt effect on the antenna, the effect of smaller size, the effect of distance from the antenna, change of SAR measurement location, and SAR level in human hands have been simulated and compared with the standard model. The simulations are all performed at 835 MHz (except for the effect of frequency change).
