AMS devices and the corresponding measured fields. Photograph of the hollow-out patterning metasurface with (a) Fermat spiral, (b) stripe, and (c) Penrose-like. Experimental intensity field generated (d) Fermat spiral patterned vortex in x–y plane at z = 8 mm, (e) stripe-patterned focusing in x–z plane, and (f) Penrose-like patterned super-oscillation in x–y plane at z = 34 mm.
