Figure | Physical Origins of Angular Dispersions and Schematics of Angle-Dependent Multifunctional

Caption

(a) By controlling the coupling between meta-atoms (upper inset) and the radiation properties of constituent meta-atoms (lower inset), one can realize angle-dependent multifunctional meta-devices with wave-control functionalities that change as the incident angle of the excitation light varies. (b) TE-TM reflection-phase difference as function of incident angle, illustrating the incident-angle-dependent polarization controllability of meta-design shown in the inset. (c) Schematics of angle-multiplexed wave-front meta-controller based on reflective metasurfaces combining with angular dispersion manipulations.
