A team of researchers at Technion—Israel Institute of Technology has developed a new technique for conducting real-time evanescent wave imaging using standard optical technology. In their paper published in the journal ...
Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses. These structures can control ...
Ever since Kepler's observation in the 17th century that sunlight is one of the reasons that the tails of comets to always face away from the sun, it has been understood that light exerts pressure in the direction it propagates. ...
