Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel
Advanced Materials Technologies, EarlyView.The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors
Advanced Optical Materials, EarlyView.Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics
Advanced Optical Materials, EarlyView.8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

Dark‐State Guided‐Mode Resonance Sensors: Engineering Miniature Sensing Platforms
Advanced Optical Materials, EarlyView.This research introduces compact guided‐mode resonance sensing using Gaussian‐beam‐induced symmetry breaking to excite dark states. The method generates high‐quality resonance signals in a small area, demonstrating a sensor with 128 micro‐cells and 200 nm RIU−1 sensitivity, showing potential for lab‐on‐chip and biosensing applications.
