a Geometrical description of the asymmetric split-ring resonator (SRR) unit cell with length (l) = 250 μm, bracket width (w) = 35 μm, capacitive gap width (c) = 35 μm, thickness (t) = 50.8 μm, gap distance (δ) = 72.5 μm or asymmetry parameter (α) = 100%, and its respective optical image (b). The arrows indicate the directions of the electric field (Ey), magnetic field (Hx), and propagation (kz).
