Advanced Materials Technologies, EarlyView.An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.
