The phenomenon of radio frequency electromagnetic energy emitted from mobile phones is widely recognized, and the specific absorption rate (SAR) measures the amount of energy absorbed by the human head. To meet SAR standards, mobile phones can be shielded. This paper utilizes COMSOL Multiphysics to model the human head and simulate SAR distribution for various head layers exposed to radiation from a CDMA 800 downlink frequency band mobile phone. The study also observes electric and magnetic fields across the frequency range and investigate five different shielding materials. The results reveal that a polyimide sheet outperforms other materials according to ICNIRP guidelines for electromagnetic radiation exposure. These findings have significant implications for the design and production of mobile phones, as well as public health and safety.
