This paper reports a multiphysics electromagnetic–thermal simulation of radiofrequency (RF) antenna exposure for a subway station attendant, estimating specific absorption rate (SAR) and temperature rise in the trunk and selected organs at 900, 2600, and 3500 MHz. Using a COMSOL-based model with a detailed human anatomy representation, the authors found simulated SAR and temperature increases that they state are well below ICNIRP occupational exposure limits. The study concludes that RF emissions from antennas in the modeled subway environment pose low health risk for female attendants with similar characteristics to the model used, while noting the work is based on simulations rather than measurements.
Parametric analysis of electromagnetic wave interactions with layered biological tissues for varying frequency, polarization, and fat thickness
This PubMed-listed study models how RF electromagnetic waves interact with a simplified three-layer tissue structure (skin–fat–muscle) across common ISM bands (433, 915, 2450, 5800 MHz), varying polarization (TE/TM), incidence angle, and fat thickness. Using a custom MATLAB pipeline combining multilayer transmission-line methods, Cole–Cole dielectric parameters, and a steady-state Pennes bioheat solution, the authors estimate reflection, absorption, and resulting temperature rise. The simulations report small temperature increases at lower frequencies (433–915 MHz) and larger superficial heating at 5.8 GHz under the modeled conditions, highlighting how fat thickness and wave parameters modulate dosimetry and thermal outcomes.
Exposure to 5G-NR electromagnetic fields affects larval development of Aedes aegypti mosquito
A PubMed-listed study examined whether exposure to 5G New Radio (5G-NR) radiofrequency electromagnetic fields (RF-EMF) at 3.6 GHz affects larval development in Aedes aegypti mosquitoes. Using a custom reverberation-chamber exposure setup and numerical simulations to estimate dose, the authors report slower development at a lower exposure level (46.2 V/m), particularly in nutritionally weakened larvae. At a higher exposure level (182.6 V/m), the study reports dielectric heating that altered development timing and adult size.
Behaviour and reproduction of Drosophila melanogaster exposed to 3.6 GHz radio-frequency electromagnetic fields
This animal study assessed whether 3.6 GHz RF-EMF exposure affects behaviour and reproduction in adult Drosophila melanogaster, using micro-CT-based digital-twin dosimetry and numerical simulations. It reports no significant changes in locomotor activity after 5 days at 5.4–9 V/m and no effect on fecundity over 48 hours at the tested absorbed power. The authors note that effects could still be possible at other exposure levels or in different developmental stages.
Thermal and SAR-Based Limits for Human Skin Exposed to Terahertz Radiation
This conference paper uses COMSOL Multiphysics simulations to evaluate thermal and SAR-based exposure limits for modeled human skin exposed to terahertz radiation (0.1–5 THz). The authors report negligible temperature increases at power densities consistent with keeping SAR below 1.6 W/kg, but note that higher power densities can yield minimal heating while producing SAR values above recognized safety thresholds. They conclude that existing sub-THz standards are not directly transferable to the full THz band and call for updated guidelines, especially for prolonged exposure.
Assessment of Electromagnetic Exposure Levels for Humans from Electric Vehicle DC Charging Stations
This simulation study modeled EMF exposure from an electric vehicle DC charging pile transformer using adult and child human models at several distances and for in-vehicle occupants during charging. Reported peak B-field and E-field values at 0.1 m and modeled internal exposures decreased with distance and remained below stated ICNIRP occupational and public limits. Frequency comparisons (85–95 kHz) indicated decreasing B-field with higher frequency while E-field stayed relatively stable. The authors note the need for real-world measurement validation and further assessment in sensitive populations and multi-source settings.
In situ electric field dosimetry analysis for powerline frequency peripheral nerve magnetic stimulation
This study used computational dosimetry to analyze induced electric fields in a realistic human body model for a 60 Hz magnetic-field exposure system targeting the leg. Simulations indicated high EF intensities in several leg nerves and modeled conditions consistent with possible peripheral nerve stimulation. The MRG model produced lower stimulation thresholds than the SENN model, and nerve orientation was reported as a key determinant of stimulation risk.
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.
Numerical Analysis of Human Head Exposure to Electromagnetic Radiation Due to 5G Mobile Phones
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 for higher-resolution models, refined tissue segmentation, longer exposure durations, and varied phone placements to better characterize potential impacts.
Assessment of Electromagnetic Exposure to a Child and a Pregnant Woman Inside an Elevator in Mobile Frequencies
This study uses anatomically detailed computational models of a five-year-old girl, a pregnant woman in the third trimester, and a fetus to simulate mobile phone RF exposure inside an elevator cabin. Simulations at 1000 MHz and 1800 MHz across 48 configurations evaluated SAR10g, whole-body SAR, and maximum temperature. The abstract reports that configuration (positioning and phone orientation) can substantially change absorption and temperature metrics and calls for broader scenario testing to inform safety guidance for vulnerable populations.
Impact of Anthropomorphic Shape and Skin Stratification on Absorbed Power Density in mmWaves Exposure Scenarios
This dosimetry study used FDTD simulations at 28 GHz to evaluate how skin stratification and anthropomorphic modeling affect absorbed power density (APD) estimates. APD was higher with stratified skin than with homogeneous skin for a wearable patch antenna (16%–30% higher), while plane-wave differences were smaller (<11%). The authors argue that simplified skin models may underestimate exposure in mmWave wearable scenarios.
Perspectives on terahertz honeybee sensing
This paper describes measurements and simulations to support terahertz (THz) sensing of European honey bees for environmental monitoring. It reports dielectric characterization of bee body parts across 1–500 GHz, scattering-based validation of 3D-printed bee mockups, and THz imaging demonstrating detailed anatomical visualization. The work includes dosimetric simulations at 300 GHz to evaluate feasibility of non-invasive, continuous monitoring and notes potential relevance to assessing high-frequency EMF impacts on insect health and habitat safety.
Auto-Induced Downlink Radiofrequency Electromagnetic Field Exposure at 3.5 GHz With Focusing Near the Head
This exposure-assessment study uses FDTD simulations to evaluate auto-induced downlink RF-EMF exposure at 3.5 GHz when downlink energy is focused toward user equipment near the head. Exposure varied substantially by device position (ear, eyes, nose) and by the precoding technique used. The authors report that the choice of normalization strategy can produce cases where ICNIRP basic restrictions are exceeded even when reference levels appear compliant, motivating a precautionary framing for compliance assessment.
Protective effects of quercetin against 3.5 GHz RF radiation-induced thyroid dysfunction and oxidative stress in rats
This rat study examined repeated 3.5 GHz RF exposure (2 hours/day, 5 days/week for 30 days) and thyroid-related outcomes, with and without quercetin. The abstract reports altered thyroid hormones (lower T3/T4, higher TSH) and increased oxidative stress in thyroid tissue after RF exposure. Quercetin appeared partially protective, though effects were not uniformly statistically significant, and SAR simulations indicated relatively higher absorption in the thyroid region.
Assessment of RF EMF Exposure to Car Driver from Monopole Array Antennas in V2V Communications Considering Thermal Characteristics
This modeling study assessed RF-EMF exposure from a 5.9 GHz V2V monopole array antenna integrated into a car roof shark-fin antenna. Using COMSOL simulations with an adult male body model inside a vehicle, the authors estimated localized and whole-body SAR and associated core temperature rise over a 30 min averaging period. Reported SAR and temperature rise values were below ICNIRP occupational thermal-based restrictions, leading the authors to conclude the exposure does not pose a threat under the studied conditions.
Impact of a Terahertz electromagnetic field on the ion permeation of potassium and sodium channels
This biophysics study used molecular dynamics simulations to examine how terahertz electromagnetic fields affect ion permeation in voltage-gated potassium (Kv1.2) and sodium (Nav1.5) channels. The simulations report increased ion permeability at several specific terahertz frequencies, with effects depending on field frequency and direction and increasing with field amplitude. The authors frame these results as evidence of specific EMF–ion channel interactions with potential health relevance and possible biomedical applications.
