In the present work, we provide a methodology for dosimetry evaluation when a human body is exposed to a high-intensity broadband frequency signals. By performing numerical simulation on a scenario representing a detailed numerical model of human body, with the presence of a source in its proximity, we obtained a set of worst-case frequencies, in order to give a guideline to fast-up the Specific Absorption Rate (SAR) measurements. Furthermore, we observed how the hotspots along the human body change their position according to the frequency, also giving us a method for optimizing probe positioning.

Abstract
In the present work, we provide a methodology for dosimetry evaluation when a human body is exposed to a high-intensity broadband frequency signals. By performing numerical simulation on a scenario representing a detailed numerical model of human body, with the presence of a source in its proximity, we obtained a set of worst-case frequencies, in order to give a guideline to fast-up the Specific Absorption Rate (SAR) measurements. Furthermore, we observed how the hotspots along the human body change their position according to the frequency, also giving us a method for optimizing probe positioning.File in questo prodotto:
