Radiated Effect of Mobile phone Electromagnetic and Defense
Abstract: According to the electromagnetic theory and the definition of specific absorption rate, the method of measurement for mobile phone electromagnetic radiation is simplified. With experimental measurements and numerical simulation analysis of the electromagnetic radiation power density in the several different types of mobile phones use state, the general rules of mobile phone electromagnetic radiation are summarized. Mobile phone electromagnetic radiation when phone is switched is few times to normal call, brand mobile phone radiation irrelatively weak, and the mobile phone on moving has more electromagnetic radiation than phone at a standstill are found. Put forward countermeasures and suggestions to reduce the influence of mobile phone electromagnetic radiation on the human.
Key Words: Mobile phone electromagnetic radiation; Specific absorption rate; Radiation electromagnetic and power density
