[56] Special issue on "Metasurfaces: Physics and Applications" F. Ding, P. Genevet and S.I. Bozhevolnyi, Applied Sciences, 8, 1727 (2018) This special issue is launched to provide a possibility for researchers in the area of metasurfaces to highlight the most recent exciting developments and discuss different metasurface configurations in depth, so as to further promote practical applications of metasurfaces.
CRHEA, in collaboration with the center of the CNRS International NTU THALES Research Alliance in Singapore, presents a method for designing ultrathin optical components - commonly called metasurfaces - of arbitrary shapes. The method relies on an optical transformation technique used in the field of metamaterials. With this results, it is now possible of predicting and designing the optical response of metasurfaces conformal to non-planar objects. This method would enable new design opportunities for free-form optics, illusion optics, radar and military camouflage.
