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 ...

It’s all to do with the raindrops, says one reader, with them needing to be relatively uniform in size and well separated for ...

Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental manipulation of waves. Contrarily to static systems, which exhibit the same ...

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 ...
