Metasurfaces are artificial structures, composed of periodic arranged of meta-atoms at subwavelength scale. Meta-atoms are made of traditional materials but, if they are placed in a periodic manner, the surface can show many unusual effects that cannot be realized by the materials in nature. In their article published 15 February 2019 in Science Advances, the researchers use power-flow conformal metasurfaces to engineer the direction of reflected waves.

'Existing solutions for controlling reflection of waves have low efficiency or difficult implementation,' says Ana Díaz-Rubio, postdoctoral researcher at Aalto University. 'We solved both of those...
