How to Manufacture Photonic Metamaterials
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

A Type I Hyperbolic Metamaterial Driven by Phonons on ZnO
This article reports the first realization of a phonon‐driven type I hyperbolic metamaterial with ZnO/(Zn,Mg)O heterostructures. By adjusting the Mg content and layer thickness ratio, it establishes a clear framework for achieving and tuning the type I hyperbolic region via phonon resonances.

Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering
Femtosecond laser surface processing (FLSP) is employed to fabricate titanium‐based metamaterials with engineered micro/nano‐scale features that exhibit spectrally selective and omnidirectional thermal emissivity. By integrating advanced ellipsometry, electromagnetic modeling, and compositional analysis, the work reveals resonance‐driven emissivity ...

In this study, the pronounced anisotropy in the optical properties of β‐Ga2O3 nanomembranes has been analized under a synchrotron nanoprobe. We have investigated the site‐specific contributions of distint Ga ions to the emission bands by combining polarization‐dependent X‐ray absorption near‐edge structure and X‐ray excited luminescence.
