Wireless Electromagnetic Radiation Assessment Based on the Specific Absorption Rate (SAR): A Review Case Study

Employing electromagnetic fields (EMFs) in new wireless communication and sensing technologies has substantially increased the level of human exposure to EMF waves. This paper presents a useful insight into interaction with biological media that is defined by heat generation due induced currents dielectric loss. The specific absorption rate (SAR) defines heating amount medium irradiated an field value. reviews radio frequency hazards SAR based on various safety standards organisations, including detailed investigation previously published work terms modelling measurements. It also summarises most common techniques utilised between 1978 2021, operational spectrum, bandwidth, values.
