Abstract

Due to the rapid growth in the use of wireless communication systems, there has been a recent increase in public concern regarding the exposure of humans to radio frequency (RF) electromagnetic radiation. This is particularly evident in the case of mobile telephone handsets. This paper aims to provide an investigation of the effectiveness of various commercially available Specific Absorption Rate (SAR) reduction products and shielding materials that can be externally attached to the handsets in Hong Kong. Also, the SAR values of different mobile phones are measured. Results are compared to the USA and European standards and then characterized for SAR reduction applications.
