Liquid‐Crystal‐Based Reconfigurable Intelligent Surface for 7 GHz Mobile Communication
Advanced Materials Technologies, EarlyView.The glass‐based liquid‐crystal reconfigurable intelligent surface (LC‐RIS) integrates active‐matrix driving and blind‐greedy phase optimization within a 5G‐NR OFDM framework. This enables continuously tunable and autonomous enhancement of wireless coverage. Leveraging the transparency and manufacturability of liquid crystal panels, it is ideally suited

Advanced Optical Materials, EarlyView.Comparing Fabry–Perot and plasmonic nanorod cavities reveals how the number of dark states dictates polariton relaxation. The high number of dark states results in a polaritonic bottleneck, while reducing the number of dark states enables to measure the polaritonic decay.

Reduction of the Instrument Model Error in Aperture Synthesis Radiometers
IEEE Access, 2018 Aperture synthesis radiometers measure the visibilities of the scene under observation by an antenna array, and based on these visibility measurements, inverse algorithm is employed to reconstruct the brightness temperature of the observed scene.

Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control
Advanced Optical Materials, EarlyView.This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.

Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light–Matter Coupling
Advanced Optical Materials, EarlyView.Transferable dielectric distributed Bragg reflectors enable the deterministic assembly of high‐quality planar microcavities while maintaining the intrinsic properties of quantum materials during fabrication. The resulting structures exhibit robust exciton‐photon coupling in monolayer WS2${\rm WS}_{2}$ from cryogenic to room temperature, establishing a ...
