Liquid‐Crystal‐Based Reconfigurable Intelligent Surface for 7 GHz Mobile Communication

ABSTRACT Reconfigurable Intelligent Surfaces (RIS) offer a promising solution to mitigate signal blockages by dynamically shaping the wireless environment. Yet, large‐area deployment is still constrained by scalability, power consumption, and integration complexity. This paper in...

Electrohydrodynamically Driven Broadband and Color‐Shifting in Cholesteric Liquid Crystals

ABSTRACT Rapid, multimode photonic bandgap tuning of cholesteric liquid crystals (CLCs) is achieved by harnessing ion‐driven electrohydrodynamic (EHD) effects. By utilizing CLCs with negative dielectric anisotropy doped with ions and applying low‐frequency AC voltage, two distinc...
