This report concerns with the theoretical studies of SPP Bloch waves in arrays of cylindrical holes. Most analytical solutions are simplified, approximate and fitted, thus leading to wrong design parameters. A rigorous analytical solution that can accurately predict the desired dimensions associated with hole arrays is complex to derive. Finite element analysis (FEA), on the other hand, offers extensive capabilities for modelling and simulating the response of periodic structures such as that…

Effect of the plasmonic dispersion relation on the transmission properties of subwavelength cylindrical holes

We analyze subwavelength cylindrical holes in an optically thick metallic film with the metal described by a plasmonic model. We find that the dispersion diagram exhibits three distinct features that

Microscopic theory of the extraordinary optical transmission

TLDR
A microscopic theory of the transmission through subwavelength hole arrays is derived, by considering the elementary processes associated with scattering of surface-plasmon-polariton (SPP) modes by individual one-dimensional chains of subwa wavelength holes, and derives analytical expressions for all the transmission spectrum characteristics.

Colloquium: Light scattering by particle and hole arrays

This Colloquium analyzes the interaction of light with two-dimensional periodic arrays of particles and holes. The enhanced optical transmission observed in the latter and the presence of surface

Quasi-cylindrical wave contribution in experiments on extraordinary optical transmission

TLDR
From the measured transmission spectra, microscopic scattering parameters are determined which allow us to show that quasi-cylindrical waves affect EOT only for high densities, when the hole spacing is roughly one wavelength.

Surface plasmons enhance optical transmission through subwavelength holes

Optically thick metal films perforated with a periodic array of subwavelength holes show exceptional transmission properties. The zero-order transmission spectra exhibit well-defined maxima and

TLDR
A comprehensive microscopic model of the EOT that takes into account the two surface waves and provides highly accurate predictions over a much broader spectral range, from visible to microwave radiation.

Surface plasmon polaritons and their role in the enhanced transmission of light through periodic arrays of subwavelength holes in a metal film.

TLDR
Results of the transmitted, reflected, and absorbed power associated with the enhanced transmittance of light through a silver film pierced by a periodic array of subwavelength holes shows that the transmission features of the array are consistent with p-polarized resonant modes of the structure.

Transmission resonances through aperiodic arrays of subwavelength apertures

TLDR
This work demonstrates experimentally that, in contrast to the conventional view, sharp transmission resonances can be obtained from aperiodic aperture arrays, and expands potential design parameters for aperture arrays that are a periodic but contain discrete Fourier transform vectors, and opens new avenues for optoelectronic devices.

Propagating plasmonic mode in nanoscale apertures and its implications for extraordinary transmission

We studied the interaction of different pathways by which extraordinary transmission through nanoscale aperture arrays arises and obtained a complete physical picture that incorporates both

Role of Wood anomalies in optical properties of thin metallic films with a bidimensional array of subwavelength holes

Recents works dealt with the optical transmission on arrays of subwavelength holes in a metallic layer deposited on a dielectric substrate. Making the system as realistic as possible, we perform
