Transparent White OLED‐Based Brain Stimulation With Invisible Flicker and Photobiological Safety Evaluation

open access: yesJournal of the Society for Information Display, Volume 34, Issue 5, Page 264-272, May 2026.
A safe, transparent, invisible flickering transparent white OLED (TrWOLED) platform is developed for therapeutic 40 Hz brain stimulation. By utilizing chromatic modulation, this device delivers effective gamma frequency brain entrainment while eliminating visual fatigue.

A Study of Gas and Rain Propagation Effects at 48 GHz for HAP Scenarios

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
The atmosphere and rainfall significantly limit the performance of millimeter wave links and this has to be taken into account, particularly, during planning of high altitude platform (HAP) networks.

Ultra-thin optical power converters based on Gires–Tournois resonator configuration operating in high-order modes

open access: yesApplied Physics Express
In this study, we propose a strategy to construct high-performance ultra-thin optical power converters (OPCs) based on Gires–Tournois resonator configurations operating in high-order modes. Despite reducing the absorber thickness by 5.8 to 8.1 times, the
