This feasibility study reports numerical modeling and HFSS simulations of a portable meander line antenna intended to deliver repeated electromagnetic field stimulation at 64 MHz for potential Alzheimer's disease treatment. Using two numerical head phantoms, the authors simulated E/H fields and SAR with a 50-W input…

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…

This laboratory/analytical study examined how sample matrix affects sample sweeping in micellar electrokinetic chromatography under an inhomogeneous electric field. It reports strong focusing for hydrophobic cationic analytes when the sample matrix conductivity is much higher than the BGE, even with low surfactant…

This engineering/physical chemistry study develops an analytical model and uses computer simulations to describe the electric field in oxide films during thermal metal oxidation. It reports that the electrostatic potential drop across the bulk oxide is often limited to about kBT/e, suggesting most of a larger overall…

This engineering study used experiments, computer simulations, and simplified analytical calculations to examine how mashed potato dielectric properties and circulating water electrical conductivity affect RF heating at 27 MHz. The authors report that higher circulating water conductivity and higher salt content in…
