PubMed: RF-EMF health
Dec 26, 2025
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…

Jan 1, 2025
This numerical dosimetry study modeled localized RF exposure (3–30 GHz) in multi-layer human skin constructs including skin, fat, and muscle, with an added synthetic blood vessel model. Vascular modeling had negligible impact on peak spatial-averaged absorbed power density and a modest impact on peak temperature rise…

Jan 1, 2024
This pilot animal study examined ELF-EMF exposure (0.1 or 1.0 mT, 1 h/day up to 5 weeks) in sedentary adult male C57BL/6 mice, with or without N-acetyl-cysteine (NAC) supplementation. The authors report a transient increase in muscle strength after 2 weeks at 1.0 mT, accompanied by higher PAX7 and myosin heavy chain…

Jan 1, 2023
This mouse study tested whether alternating current electromagnetic field (EMF) exposure modifies muscle lipid accumulation during long-term high-fat feeding. Mice exposed to EMF (8 hours/day for 16 weeks; maximum 180 mT) while on a high-fat diet had lower intramyocellular lipid levels than high-fat diet controls.…

Jan 1, 2022
This animal study evaluated whole-body EMF stimulation in a rat model of complete spinal cord injury. Compared with SCI alone, EMF exposure for 7 or 14 days was reported to improve electrophysiological measures of motor neuron excitability and enhance soleus muscle contractile performance. Histopathology and protein…

RF Safe Research Library
Jan 1, 2018
This paper analyzes how conservative current localized RF EMF SAR basic restrictions may be by estimating the implied safety factor. The authors derive thermal dose–functional SAR limits from literature-reported thresholds for acute local tissue damage and compare these to existing basic restrictions. They report…

Jan 1, 2015
This engineering/food science study measured dielectric constant (ε'), dielectric loss factor (ε″), and power penetration depth in beef and gravy preparations across 27–1,800 MHz and 20–130 °C. The dielectric properties generally decreased with increasing frequency, and penetration depth decreased with increasing…

This animal study examined in vivo and in vitro effects of weak, low-frequency magnetic fields described as having resonance parameters for calcium ions. The authors report a considerable decrease in activity of calcium-dependent proteinases (calpains) in fish skeletal muscle and brain following exposure. The…
Comparison of 2 methods of non-invasive treatment between transcutaneous electrical stimulation and pulsed electromagnetic field stimulation as replacement of invasive manual acupuncture.
