Transmission of light through a single rectangular hole.
TLDR
It is shown that a single rectangular hole in a metallic film exhibits transmission resonances that appear near the cutoff wavelength of the hole waveguide, and this resonant transmission process is accompanied by a huge enhancement of the electric field at both entrance and exit interfaces of thehole.Abstract:
We show that a single rectangular hole in a metallic film exhibits transmission resonances that appear near the cutoff wavelength of the hole waveguide. For light polarized with the electric field pointing along the hole's short axis, it is shown that the normalized-to-area transmittance at resonance is proportional to the ratio between the long and short sides, and to the dielectric constant inside the hole. Importantly, this resonant transmission process is accompanied by a huge enhancement of the electric field at both entrance and exit interfaces of the hole.read more

TL;DR: It is shown that extraordinary light transmission of periodic subwavelength hole arrays, generally attributed to surface-plasmon resonances, is strongly influenced by the hole shape, and shape resonances of the rectangular holes play a dominant role.

Strong polarization in the optical transmission through elliptical nanohole arrays.
TL;DR: Strong polarization dependence is observed in the optical transmission through nanohole arrays in metals and the depolarization ratio shows a squared dependence on the aspect ratio of the holes, which is discussed in terms of coupling into and out of the surface plasmon modes.
