Design of transmission-type Huygens’ metasurface and experimental setup. a Geometric structure of the proposed Huygens’ meta-atom patterned on both sides of the dielectric substrate (εr = 2.2, tan δ = 0.002). b Surface currents and equivalent electric circuits of the proposed meta-atom. c Simulated transmission amplitude and phase of 15 extracted meta-atoms with different geometrical parameters, lm and le at 10 GHz. d Experimental setup utilized for characterizing the metasurface hologram. The right side is a zoomed-in view of the fabricated Huygens’ metasurface
