Abstract: The capability to manipulating electromagnetic (EM) waves at the sub-wavelength scale has been enabled by metamaterials and their two-dimensional counterparts, metasurfaces. Especially, integrating two or more diverse functionalities into a single metasurface-based device is of… read more here.

DOI: 10.1364/oe.455617
Abstract: Aggressive discretization in metasurface design-using the least number of unit cells required-can dramatically decrease the phase coverage requirement, thus allowing the use of simple structure and avoiding unit cells with strong resonance, leading to a… read more here.
