This engineering/modeling study developed a 3D myelin microstructure model using finite element analysis and high-resolution imaging to simulate local electromagnetic field distributions. It reports that myelin architecture substantially shapes the distribution of electromagnetic fields across neural tissues. The authors suggest these field variations could potentially serve as non-invasive indicators of myelin integrity and may support tracking neurodegenerative disease progression.
The modeling of the interaction of pulsed 5G/6G signals and the fine structure of human skin
This paper uses advanced electromagnetic simulations of human skin microstructure to model exposure to realistic pulsed 5G/6G signals at 3.5, 27, 77, and 300 GHz. It reports localized, inhomogeneous absorption patterns linked to sweat glands and blood vessels, suggesting that treating skin as homogeneous may miss hotspots. The authors conclude that SAR-based standards may be inadequate for mmWave/sub-THz exposures and could underestimate potential risks, including possible nerve excitation.
