Figure | The analysis of Spatial Harmonic-expanded Generalized Snell's Law (SH-GSL).  a, The schematic of the deterministic Floquet-engineered momentum compensation mechanism. By engineering the incident angle and compensation wave vector, each spatial harmonic can be confined in the plasmonic zone or radiative zone, thereby enabling different manipulations. b, The relationship of the incident angle and the compensation wave vector. Different regions represent the radiative zones of different harmonics, and out-of-region means that the harmonic is localized on the surface. c, The relationship of incident and reflective angles of different harmonics after designing the compensation wave vector (0.8k0) of the metasurface.
