Dosimetry Computation Based on Near-Field Measurements on a Huygens Box Surrounding the Antenna

This article presents a new technique for dosimetry assessment in realistic environments based on free-space EM-fields' measurements around the antenna thanks to a RF phasor array embedded in an EM scanner. These measured EM-fields are used in the simulation as a Huygens' box source to model the radiation from the EM-device. Note that in practice -except for the manufacturers of the EM device- the challenge is that we do not know the full details of the EM-device concretely. Such knowledge is necessary in any simulation process containing the device. The coupling of RF phasor near-field measurements with simulations (augmented measurements) are done by keeping a turned off simplified replica of the EM-device inside the Huygens' box to model the interactions between the human model and the EM-device (e.g., scattering and diffraction). Numerical simulations are done with the Finite Integration Technique (FIT) to test the accuracy and validity of the proposed approach.
