This narrative review focuses on RF exposure in military contexts, emphasizing thermal effects as the established mechanism of harm and discussing safety limits set by bodies such as ICNIRP and IEEE. It reports that whole-body SAR limits (≤4 W/kg) generally prevent dangerous core temperature rises, but localized…

This engineering study describes and simulates a helmet radio-frequency phased array applicator for Thermal Magnetic Resonance (ThermalMR), which combines MRI with targeted RF heating. Using EMF and temperature simulations in a phantom and human head model (including a modeled glioblastoma tumor volume), the authors…

This in vitro study describes a microfluidic device integrated with a radiofrequency exposure system to enable on-chip monitoring of cellular responses under a 1.8 GHz field. Using human amniotic epithelial cells, the authors report field-intensity-associated increases in protrusions/filopodia, changes in…

This engineering/simulation study evaluates RF applicator array designs for Thermal Magnetic Resonance (ThermalMR), which combines MRI with RF hyperthermia for brain tumor theranostics. Using EMF and temperature simulations at 7.0 T, 9.4 T, and 10.5 T, hybrid loop+SGBT dipole arrays are reported to provide superior…

This exposure assessment measured RF-EMF levels in 21 state hospitals in Samsun Province, Turkey using short-term, long-term, and band-selective approaches across 100 kHz–3 GHz (total) and 27 MHz–3 GHz (band-selective). The study reports that the ICTA 3 V/m limit was exceeded in at least some hospital measurements,…

This study reports a technology that records a specific radiofrequency electromagnetic energy signal associated with EGFR siRNA and applies it to cells. The abstract describes reductions in EGFR mRNA and protein expression versus controls, with specificity assessed using RNA microarray and antibody dot blot array. It…

This in vitro study describes a method to improve DNA ligation by immobilizing T4 DNA ligase on ferromagnetic particles and applying a radio frequency alternating magnetic field. The field causes the particles to dissipate heat, which the authors report selectively heats and activates the ligase while minimally…

This engineering study deposited Ga-doped ZnO thin films via radio frequency sputtering and examined how Ga content affects optoelectronic properties and electrical stability. The abstract reports non-monotonic changes in conductivity with increasing Ga content alongside degraded crystallinity, while maintaining >80%…

This engineering paper demonstrates an auto-tuning method for a high-sensitivity RF interferometer using a tunable liquid attenuator controlled by liquid volume. The authors report an effective quality factor up to 1×10 at ~5 GHz and a self-calibration/measurement process from 2 to 7.5 GHz using a methanol-water…

This engineering study investigated RF-induced power deposition near straight insulated leads in an MRI context under different incident electric field profiles. Using 3-D electromagnetic simulations, the authors compared simulation-derived power deposition with implant model predictions. For the setups examined,…

This conference paper describes a peri-implantitis therapy using radio frequency electric current and presents numerical simulations alongside referenced clinical evidence. The abstract reports 81% successful treatment across 66 implants in 46 patients. FEM modeling suggests current preferentially concentrates in…

This engineering study investigated RF-induced power deposition from insulated leads of different lengths positioned near two surrounding tissues. The authors report that both the electromagnetic lead models and the resulting power deposition depended strongly on the electrical properties of both tissues. Using a…

This engineering study uses a 3D electromagnetic solver to simulate in-to-out body RF path loss for a wireless capsule endoscopy link. The capsule antenna is tuned for the 402 MHz MICS band while accounting for human body properties. The authors examine how capsule misalignment, rotation, and the human body model…

This engineering-focused conference paper characterizes thrombus stiffening after radio frequency (rf) electric current treatment in the context of intra-arterial mechanical thrombectomy. The abstract reports thrombus stiffness increased by more than eightfold after rf treatment, attributed to increased crosslinking.…

This study enrolled 70 patients with primary hyperthyroidism and 74 healthy volunteers and assessed carotid artery structure and function using ultrasound RF data parameters before and after 131I therapy. Hyperthyroid patients showed worse carotid IMT and stiffness-related measures than controls at baseline. After…

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 engineering paper describes a fiber-based method for stable radio-frequency dissemination using a hybrid frequency modulation approach. Two RF components are transmitted simultaneously using a single laser diode, with one component used for phase fluctuation detection and the other providing a compensated stable…

This engineering/materials study examined how RF magnetron sputtering power affects the structural and optical properties of In2S3 thin films intended as a CdS buffer substitute in CIGS solar cells. Films deposited at 60–120 W were characterized using XRD, AFM, EDS, and UV-visible spectrophotometry. The films were…
