“Patch-to-SRR” morphing.
(a) “Patch-to-SRR” route for topological morphing of the metasurface pattern and (b) simulated performance of corresponding uniform-metasurface-based reflectarrays at the frequency of 0.35 THz. The exciting polarization is transverse to USR and SRR slots. The geometric parameters are given in micrometers. Metallization is shown in orange (dark).
