Experiments to validate a technique for reducing the human RF exposure from mobile terminals

Reduction of human exposure to electromagnetic radiation generated by mobile phones terminals is a major concern both for equipment manufacturers and users. Reduced fares and technological development (antenna integration, energy consumption decrease, etc) led to an unprecedented increase of phone call duration with yet unknown consequences on human beings and especially on children. The authors identified a method intended to reduce the Specific Absorption Rate (SAR) of electromagnetic radiation with no influence on the emission/ reception properties of mobile phone terminal. The paper presents the said method and the experiments performed to validate it. To this end, measuring systems were used both for compliant and noncompliant measurements on mobile phones terminals of different generations.
