Design for Highly Efficient Nanometagratings and Theory of Extreme Subdiffraction Photon Control
Conventional planar metasurfaces are always much larger than the wavelength level. Previous studies on extreme wavefront control based on superoscillation suggest a fundamental tradeoff between the size and efficiency of diffraction‐based metasurfaces. Herein, the theory of extreme subdiffraction ph...
