Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial

Advanced Materials Technologies, EarlyView.
A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...

When Cellulose Moves: Smart Sensors and Actuators

Advanced Materials Technologies, EarlyView.
This review highlights cellulose‐derived soft actuators alongside with cellulose‐based sensors. Emphasis is placed on their integration into multifunctional devices that couple sensing and actuation to mimic natural motion and adaptability. We also discuss the challenges of achieving robust, reversible, and multi‐stimuli‐responsive motion, and outline ...

A Multi‐Resonant Tunable Fabry‐Pérot Cavity for High Throughput Spectral Imaging

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study introduces a multi‐resonant tunable Fabry‐Pérot filter for high throughput spectral imaging. With a spectral resolution of 10 nm and a switching time of 23 ms, this compact and low‐cost device possesses better spectral imaging accuracy in poor light conditions while maintaining over six times higher optical throughput than standard liquid ...

On‐Chip Control of Electron Emission with an Active Terahertz Metasurface

Advanced Optical Materials, EarlyView.
A THz pulse drives Fowler‐Nordheim electron emission from gold dipole antennas. Changing the on‐chip DC bias bends the electron path toward or away from the bias pads. Abstract Terahertz (THz) radiation has emerged as a powerful tool for inducing ultrafast electron emission and controlling electron beams, with applications in photonics and electron ...
