Impacts of RF Radiation on the Human Body in a Passive RFID Environment
Source: University of Texas
The characterization of RF propagation is a theoretical method for evaluating the workings of electromagnetic radiation in a given environment. Recently, there have been numerous explorations of the fundamental characterizations of passive Radio Frequency Identification (RFID) systems in electromagnetic structures. These studies have concentrated on various topics not limited to the holy grails of passive RFID systems, i.e. metallic and moist environments. Because of the nature of passive systems, attenuation in these environments is relatively high and often causes an RFID tag to hover towards the no-read zones. This is typically propelled by the lack of power being harvested by the tag or attenuation of the tag reply signals.
