Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

Conventional optical components such as lenses, waveplates and holograms rely on light
propagation over distances much larger than the wavelength to shape wavefronts. In this …

BACKGROUND Metasurfaces have opened up a number of remarkable new approaches to
manipulate light. These flat optical elements are constructed from a dense array of strongly …

The mechanical properties of ordinary materials degrade substantially with reduced density
because their structural elements bend under applied load. We report a class of …

Metasurfaces have enabled a plethora of emerging functions within an ultrathin dimension,
