Abstract

As mobile phones have become a necessity in modern society, and there is an increasing number of users of various ages, it is imperative to investigate the impact of mobile phone radiofrequency electromagnetic radiation (RF) on humans. Because the human head is one of the most exposed and sensitive organs in the body, this paper investigated the propagation of the electromagnetic (EM) field through it. Additionally, the Specific absorption rate (SAR) was examined to study how RF radiation affects the human head. A program code using the finite-difference time-domain (FDTD) method was created to simulate the propagation of RF radiation through the six layers that make up the human head (skin, fat, bone, dura mater, CSF, and brain). RF radiation at the following frequencies was investigated: 0.9 GHz, 1.8 GHz, 2.4 GHz, 3.35 GHz, and 4.5 GHz. Values of the thickness and parameters of the layers can also be changed in the program. It was discovered that the majority of the EM energy is absorbed in the skin of the human head.
