In this paper, the transmission of light through a subwavelength hole drilled in a metallic thin film is calculated by numerically solving Maxwell's equations both for a simple hole and for a hole with additional structure.Abstract:
The transmission of light through a subwavelength hole drilled in a metallic thin film is calculated by numerically solving Maxwell’s equations both for a simple hole and for a hole with additional structure. A maximum in the transmission cross section is observed for hole diameters of the order of but smaller than the wavelength. Transmission cross sections well above the hole area are shown to be attainable by filling the hole with a high-index material. The effect of adding a small particle inside the hole is also analyzed.read more

Light in tiny holes
Cyriaque Genet,Thomas W. Ebbesen +1 more
TL;DR: The presence of tiny holes in an opaque metal film leads to a wide variety of unexpected optical properties such as strongly enhanced transmission of light through the holes and wavelength filtering, which are now known to be due to the interaction of the light with electronic resonances in the surface of the metal film.

TL;DR: In this article, the optical properties of submicrometre cylindrical cavities in metallic films were explored and it was shown that arrays of such holes display highly unusual zero-order transmission spectra at wavelengths larger than the array period, beyond which no diffraction occurs.

Negative role of surface plasmons in the transmission of metallic gratings with very narrow slits
Qing Cao,Philippe Lalanne +1 more
TL;DR: It is shown that the surface plasmon contribution is not the prime effect and that waveguide mode resonance and diffraction are responsible for the extraordinary transmission of metallic grating with very narrow slits and the transmittance of subwavelength metallic gratings is always nearly zero.
