Light is often thought to reflect from a flat surface at the same angle at which it is incident. Nature Photonics spoke to Han Woerdman about the observation of angular deviations of reflected beams.

Complete control of spatially propagating waves (PWs) and surface waves (SWs) is an ultimate goal that scientists and engineers seek for, in which negative reflection of PW and negative surface wave ...

If the government continues to refuse to either eliminate the law regulating the so-called day of reflection or ensure it applies across the board, at the next general election all Malta’s newspapers ...
