Electromagnetic Exposure from RF Antennas on Subway Station Attendant: A Thermal Analysis

Research PubMed: RF-EMF health Jan 28, 2026

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…

Effect of fat thickness on subcutaneous temperature field under monopolar radiofrequency

Research PubMed: RF-EMF health Jan 19, 2026

This PubMed-listed study models and experimentally validates how subcutaneous fat thickness affects temperature distribution during monopolar radiofrequency (RF) treatment used for skin tightening and tissue repair. Using finite element analysis (COMSOL) and in vitro pork tissue experiments, the authors report that…

Thermal and SAR-Based Limits for Human Skin Exposed to Terahertz Radiation

Research RF Safe Research Library Jan 1, 2025

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…

Assessment of RF EMF Exposure to Car Driver from Monopole Array Antennas in V2V Communications Considering Thermal Characteristics

Research RF Safe Research Library Jan 1, 2025

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…

Electromagnetic Field Analysis of Low-Magnitude High-Frequency Vibrator with Multiple Plungers.

Research RF Safe Research Library Jan 1, 2018

This conference paper describes an engineering design for a low-magnitude high-frequency vibrator with multiple plungers, aiming to minimize electromagnetic fields during vibrational stimulation experiments. The authors analyze the device’s EMF using finite element methods in COMSOL. No direct biological or health…

Influence of the on-line ELF-EMF stimulation on the electrophysiological properties of the rat hippocampal CA1 neurons in vitro.

Research RF Safe Research Library Jan 1, 2017

This paper describes an on-line ELF magnetic stimulation setup and evaluates coil field distribution using COMSOL simulations alongside physical measurements. The authors report that modeled and measured magnetic flux densities were similar, and that stimulation induced sodium channel currents and fEPSPs in rat…

Antenna Design and SAR Analysis on Human Head Phantom Simulation for Future Clinical Applications.

Research RF Safe Research Library Jan 1, 2017

This study developed a mathematical and computer simulation model to analyze RF-EMF exposure in a human head phantom, motivated by potential therapeutic applications. The modeled exposure used a Yagi-Uda antenna at 64 MHz with SAR 0.6 W/kg and compared field distribution using one versus four antennas. COMSOL Bioheat…
