Numerical assessment of the induced SAR within humans due to EM radiations from Smart Meters
Absorption of electromagnetic waves emitted by smart meters has been investigated by using numerical models representing a sample of the population: namely, a 23-year old female (NAOMI), a 34-year old male (NORMAN) and a 7-year old child (Eartha). Absorption within each of the models has been assessed at two different frequencies representing the ZigBee (2450MHz) and general purpose telemetry (868MHz) band. Frequency-dependent and age-dependent tissue properties have been taken into consideration within each model. The Specific Energy Absorption Rate (SAR) induced inside each heterogeneous voxel model has been calculated with 1W input power, fed to an optimised antenna similar to that used in commercial devices. Preliminary results of the 2450MHz source depict that whole body SAR values are well under the limits specified by ICNIRP guidelines.
