The diagram of superconducting subwavelength hole array and elementary HW scattering processes involved in EOT phenomenon.

(a) The diagram of the transmission of pulsed THz radiation through W2.5. The hole length and width of W2.5 are 100 and 2.5 μm respectively. The periodicity of the hole array is 120 μm. (b) The transmission and reflection of the fundamental Bloch mode at the interface of NbN/air and NbN/MgO. (c) An incident transverse magnetic polarized (magnetic vector along y axis) plane wave being scattered by the one-dimensional hole array. (d) The scattering by hole array under illlumination of the SPP mode. (e) The fundamental Bloch mode of the hole array. (see Methods for the definition of scattering parameters of α, α′, β, t, r, ρ and τ and transmission or reflection coefficients of tA, tA', tF, rA and r′A).
