This conference paper uses numerical simulations to evaluate near-field exposure and thermal effects in a detailed human head model from a realistic 5G mobile phone operating at 26 GHz. The preliminary modeling suggests moderate, localized temperature increases in superficial tissues. The authors emphasize the need…

This engineering study describes and simulates a helmet radio-frequency phased array applicator for Thermal Magnetic Resonance (ThermalMR), which combines MRI with targeted RF heating. Using EMF and temperature simulations in a phantom and human head model (including a modeled glioblastoma tumor volume), the authors…

This modeling study estimated SAR in a multi-layer head model from a wearable IoT device’s Wi‑Fi/Bluetooth antenna. SAR was reported to be up to 10× higher when the antenna was placed in a headband versus on a helmet. The authors suggest that devices emitting below 3 mW EIRP may be considered environmentally…

This engineering/modeling study derived external electric field values from peak average 10 g SAR in a realistic human head model exposed to plane waves at 500–2500 MHz. The derived fields were compared with IEEE and ICNIRP reference levels across multiple incident directions and polarizations. The authors report…
