SAR stands for Specific Absorption Rate. It is the electromagnetic energy absorption ratio of mobile phones or wireless products, defined as follows: under the action of an external electromagnetic field, an induced electromagnetic field is generated in the human body. Because the various organs of the human body are lossy media, the internal electromagnetic field produces currents, leading to the absorption and dissipation of electromagnetic energy. SAR is commonly used in biological dosimetry to characterise this physical process. SAR expresses the electromagnetic power absorbed or dissipated per unit mass of human tissue, in W/kg.
