Jan 1, 2025
This ex-vivo experimental study tested whether electromagnetic fields from a commercial hair dryer affect microleakage of class V dental amalgam restorations in 100 extracted human teeth. Several exposure groups showed significantly higher dye-penetration microleakage scores than the unexposed control, while one…

This review discusses repeated electromagnetic field stimulation (REMFS) as a potential non-invasive therapy for Alzheimer's disease. The abstract describes reported benefits in AD mice, including reduced beta-amyloid, prevention of neuronal death, halted disease progression, and improved memory without edema or…

This commentary critiques a prior paper claiming that Brillouin precursors from 5G NR and other cellular systems could cause tissue damage deeper than the carrier-frequency penetration depth. It states that the original Brillouin precursor theory was based on nanosecond ultrawide-band RF pulses in water and that this…

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 study measured dielectric properties of beef Semitendinosus across 27, 915, and 1800 MHz and temperatures from -5 to 130 °C using an open-ended coaxial probe. The results indicate that frequency, temperature, and muscle fiber orientation influence dielectric constant, dielectric loss, and calculated penetration…

Jan 1, 2008
This engineering-focused conference paper proposes figures of merit to evaluate deep-brain transcranial magnetic stimulation (dTMS) coil designs, focusing on depth penetration, scalp stimulation, focality, and energy. It analyzes circular crown and C-core coils and reports reduced electric-field attenuation with…
