(a) Unit cell of the proposed metamaterial structure comprising of a CW and two asymmetric DCRs. The geometrical parameters are: P_x = P_y = 144, h = 500, L = 88, w = 4, L₁ = 100, L₂ = 88, a₁ = 40, a₂ = 34, d₁ = d₂ = 10 μm. (b) Schematic depicting terahertz transmission through the proposed metamaterials geometry. (c) shows optical microscope image of the fabricated sample, and (d) depicts plot of the experimentally and numerically calculated terahertz transmission spectra of the proposed MM structure for the y-polarized incident light. Solid lines represent the simulated, while dotted line corresponds to the measured transmission spectra.
