Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

As cataract surgery evolves toward a precision refractive paradigm, the accuracy of postoperative refractive prediction for intraocular lenses (IOLs) has become a core metric for surgical success.

The integration of high refractive index polymer nanocomposites has emerged as a pivotal area of research in materials science, driven by growing demands in optoelectronics, photonics and biomedical ...
