Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, Volume 38, Issue 32, 8 June 2026.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Passivated SiC Surfaces for Photonic and Quantum Applications: Balancing Chemical Stability and Surface Luminescence

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Low‐temperature passivation of SiC reveals that optical surface quality and chemical stability are not directly correlated. Ar plasma‐treated and SiNx‐passivated surfaces yield the lowest photoluminescence background, whereas CF4 plasma and ALD‐grown dielectrics introduce higher emission.

Generating Circularly Polarized Light Using Hybrid Near‐Zero and High‐Index Materials

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A flat‐optics approach to manipulating the polarization state of light is proposed using evanescent‐wave interactions in hybrid epsilon‐near‐zero and high‐index materials. The design enables linear‐to‐circular polarization conversion in a wavelength‐scale device design without depending on patterning or bulky optics and operates in both reflection and ...
