Effect of metal losses (finite conductivity) on the grating response. (a,c) Simulated transmittance spectra for different metal thicknesses (gold) for a grating with (a) W = 100 µm and (c) 500 µm. In both cases, S was set to 2 µm. (b,d) Transmittance spectra at resonance, i.e., ~ 1.1 THz and ~ 0.25 THz, when varying metal thickness for a grating with (b) W = 100 µm and (d) 500 µm. When comparing (b,d) is observed that the larger the stripe width, W, the larger the quality factor, Q, of the resonance; however, the larger the effect of metal losses, which leads to a decrease in transmission levels at the resonance as W is increased.
