Reducing the impact of electromagnetic radiation on the human head using a shielding chip for mobile phones.

According to the guidelines established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) for electromagnetic radiation exposure, polyimide sheets have been shown to outperform other materials in mitigating radiation.In the present study, MATLAB simulation software was employed to model effectiveness of polyethylene sheet in shielding head tissues from radio frequency (RF) emitted by mobile phone. The study focused on a frequency of 5 GHz, which is commonly used in modern telecommunications. The selection of this frequency allows for the investigation of the effects of higher-frequency electromagnetic fields on biological tissues. The simulation results shown in table 3 provide insights into how electromagnetic radiation from mobile phones at various 5G frequencies is absorbed by different tissues in the head. Additionally, this study explores the potential role of protective materials, such as polyethylene and metamaterials, in reducing exposure to these radiation fields.
