Figure 6

The tuning of resonance frequencies of EOT through superconducting subwavelength hole array.

(a) The temperature dependence of surface reactance of NbN film at 0.6 THz. The equivalent circuit model of localized resonance around an individual hole is plotted in inset. (b) The condition of resonant transmission for W30. The top and centre graphs show the modulus and phase of rArA' at 8.2 K obtained using HW model. The graph in the bottom shows the calculated transmission spectra using HW model. (c) The temperature dependence of the resonant transmission frequency for W30 obtained from measurement and calculation using RCWA model and F-P model.
