Study of energy absorption field emitted by generic mobile phones at 900 MHz frequency

Due to the development of electromagnetic field sources in lately increased interest in biological effects associated with exposure to electromagnetic fields used in mobile communications. In Europe, the percentage of the population using mobile phones has exceeded 80%. It is necessary for equipment to certify that they comply with European directives and, in particular, is not permissible power limits power absorbed in the human body. For example, to limit who is allowed to use mobile phones in terms of specific absorption rate, SAR (Specific Absorption Rate) is 2W/kg for human head.
