In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

ABSTRACT We discuss the polarization properties and first‐order diffraction efficiencies of volume phase holographic (VPH) transmission gratings, which can be exploited to improve the throughput of ...

A new study led by DAI Qing’s team from the National Center for Nanoscience and Technology (NCNST) of the Chinese Academy of Sciences (CAS) and Javier Abajo from the Institute of Photonic Sciences ...

A new kind of “superlens”, capable of focusing light to a spot far smaller than its own wavelength, could be far easier to build than other proposed designs, researchers say. Traditional lenses are ...
