This work presents an electromagnetic exposure intercomparison among representative human models with different body features (i.e., height, weight, and age) and genders when exposed to near-field, high-power, and broadband devices. Such devices are commonly used in the military field for communication and jamming purposes. With the aim of obtaining accurate and detailed whole-body-averaged (WBA) specific absorption rate (SAR) and 10-g SAR evaluations, a realistic scenario is numerically simulated. Three different antenna configurations are adopted, faithfully reproducing the radiative characteristics and operative frequency bands of similar devices (40&#x2013;2,700 MHz). Then, we equally expose in the working band three different human body models (Hugo, Duke, and Ella). The obtained results show that the WBA-SAR is mainly related to the total body weight, as expected from its definition. Conversely, the 10-g SAR varies along with the frequency range, and different results are observed for each human model. Guidelines for exposure reduction and physical considerations are also presented. This study can be a useful reference for conducting complete and accurate radio-frequency (RF) dosimetry analysis for such particular and high-risk devices, differentiating the study for different genders and body shapes of human body models.
