Superconductor is a compelling plasmonic medium at terahertz frequencies owing to
its intrinsic low Ohmic loss and good tuning property. However, the microscopic
physics of the interaction between terahertz wave and superconducting plasmonic
structures is still unknown. In this paper, we conducted experiments of the
enhanced terahertz transmission through a series of superconducting NbN
subwavelength hole arrays, and employed microscopic hybrid wave model in
theoretical analysis of the role of hybrid waves in the enhanced transmission.
The theoretical calculation provided a good match of experimental data. In
particular, we obtained the following results. When the width of the holes is far
below wavelength, the enhanced transmission is mainly caused by localized
resonance around individual holes. On the contrary, when the holes are large,
hybrid waves scattered by the array of holes dominate the extraordinary
transmission. The surface plasmon polaritions are proved to be launched on the
surface of superconducting film and the excitation efficiency increases when the
temperature approaches critical temperature and the working frequency goes near
energy gap frequency. This work will enrich our knowledge on the microscopic
physics of extraordinary optical transmission at terahertz frequencies and
contribute to developing terahertz plasmonic devices.
