Dispersion-engineered metasurfaces reaching broadband 90% relative diffraction efficiency

Dispersion results from the variation of index of refraction as well as electric field confinement in sub-wavelength structures. It usually results in efficiency decrease in metasurface components leading to troublesome scattering into unwanted directions. In this letter, by dispersion engineering,...
