Systematic Performance Analysis of a Propagation‐Type Metalens Under Practical Fabrication Imperfections

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
Metalenses based on dielectric metasurfaces have emerged as a powerful platform for realizing compact and multifunctional optical systems. However, the optical performance of practical devices is influenced by fabrication imperfections inherent to nanomanufacturing processes, which cause deviations from ideal design parameters.

Embedded Metasurfaces for Robust and Orientation‐Independent Imaging Applications

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
A mechanically robust metasurface is developed by embedding high‐index nanopillars within a conformal SiO2 layer. The design retains stable focusing efficiency, diffraction‐limited imaging, and bidirectional operation, while withstanding routine mechanical cleaning, enabling durable and CMOS‐compatible flat optics for practical applications ...

Mesoscale Recovery of Microglial and Neuronal Dynamics After Craniotomy Across Wide Cortex in Transgenic Mice

Advanced Science, Volume 13, Issue 23, 23 April 2026.
This study employs longitudinal fluorescence imaging in transgenic mice to map post‐craniotomy cortical recovery. We identify distinct neuroimmune recovery phases: microglial structural inflammation peaks at ∼10 days, neuronal structural intensity peaks at ∼14 days and correlates with microglial activity, and functional network modularity is most ...

XOR‐Logic Phase Coding Programmable Metasurface for Low Power‐Consumption Systems

Advanced Science, Volume 13, Issue 22, 17 April 2026.
By leveraging XOR logic, the biasing‐network complexity of 2D programmable metasurfaces is reduced from m×n to m+n through efficient row‐column control. This enables versatile functions including beam deflection and beamforming, facilitating applications in wireless communications and beyond.
