(a) Phase shift (left) and plate length (right) for the ten chosen metamaterial units (upper panel) and schematic view of one period (10 units) of the designed metasurface and the channel number corresponding to each unit (lower panel). (b) The theoretical refracted angle θt as a function of the incident angle θi , calculated by the generalized Snell’s law.
