Novel method for practical SAR determination in indoor exposure scenarios without the need for EMF measurements, based on reverberation chamber theory

We proposed and experimentally verified a novel method for determination of SAR in a dissipative object (such as a human body) exposed to EM waves in reverberating indoor environments. The method is based on power balance theory, treating the indoor environment as a reverberation chamber with a known Q factor. SAR can be determined from the power input to such room, for any object with previously known Absorption Cross Section (ACS), e.g. a typical human body in a predefined posture. Room Q factor can be determined from room characteristics, or measured case by case. This method overcomes the necessity for EMF measurements inside the room, which produce dubious results anyhow in such stochastic environments.
