Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation

open access: yesAdvanced Materials, Volume 38, Issue 3, 13 January 2026.
In this work, a universal metasurface multiplexing strategy is presented based on non‐injective transformation. By jointly optimizing two metasurfaces, multiplexed channels achieve independent wavefront control, overcoming crosstalk limits of single‐layer designs.

Full‐Domain 3D Digital Twin for Comprehensive Analysis and Validation of Standing Surface Acoustic Wave Generation on LiNbO3 Substrate

open access: yesAdvanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
A full‐domain 3D digital twin of a standing surface acoustic wave (SSAW) device on 128° YX LiNbO3 is developed and experimentally validated. The predictive power of the model is confirmed by electrical characterisation and laser Doppler vibrometry measurements, which show excellent agreement with simulations.

Phase Smoothing for Mutual Coupling Mitigation in Multifunctional Metasurfaces Designed with Diffractive Neural Networks

open access: yesAdvanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
A diffractive neural networkdesigned metasurface operating at 86 GHz generates multiple holographic patterns by controlling the phase of subwavelength unit cells. A phase‐smoothing regularization mitigates mutual coupling, enabling accurate multifunctional wavefront shaping.

Metalens Array for Complex‐Valued Optical Discrete Fourier Transform

open access: yesAdvanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
A single‐layer metalens‐array device performs complex‐to‐complex discrete Fourier transforms (DFTs) optically with O(N) digital time complexity. Integrated interferometric phase retrieval and error mitigation scheme enables accurate, compact, and low‐power optical computing. The approach provides a versatile framework for implementing arbitrary complex‐
