“…However, it was soon realized ͑Baida et al, 2004͒ that this propagating mode cannot be excited by a normally incident plane wave and it even plays a minor role for oblique incidence and p-polarized light ͑Baida, 2007͒. Instead, the transmission resonances emerging in arrays of annular holes result from the interplay between SPP modes and localized resonances that are spectrally located at the cutoff wavelength of the TE 11 mode of the annular waveguide ͑Orbons and Roberts, 2006; Lomakin et al, 2007͒. Through an optimization of parameters, absolute transmissions were predicted up to 90% for arrays with a significant "opaque" area.…”

This review provides a perspective on the recent developments in the transmission of light through subwavelength apertures in metal films. The main focus is on the phenomenon of extraordinary optical transmission in periodic hole arrays, discovered over a decade ago. It is shown that surface electromagnetic modes play a key role in the emergence of the resonant transmission. These modes are also shown to be at the root of both the enhanced transmission and beaming of light found in single apertures surrounded by periodic corrugations. This review describes both the theoretical and experimental aspects of the subject. For clarity, the physical mechanisms operating in the different structures considered are analyzed within a common theoretical framework. Several applications based on the transmission properties of subwavelength apertures are also addressed.

“…This effect is referred to as the enhanced transmission of light. The enhanced transmission effect also occurs with periodic arrays of holes [42]- [46], and has been realized not only at optical frequencies but at lower microwave and millimeter-wave frequencies [47]- [53]. In this paper, however, the focus is on the single hole.…”

The Fundamental Physics of Directive Beaming at Microwave and Optical Frequencies and the Role of Leaky Waves

| This review paper summarizes various aspects of directive beaming and explains these aspects in terms of leaky waves. Directive beaming occurs in antenna design where a narrow beam is obtainable by using fairly simple planar structures excited by a single source. These structures include Fabry-Pérot cavity structures as well as metamaterial structures made from artificial low-permittivity media. Directive beaming also occurs in the optical area where it has been observed that highly directive beams can be produced from small apertures in a metal film when an appropriate periodic patterning is placed on the film. One aspect that these phenomena all have in common is that they are due to the excitation of one or more weakly attenuated leaky waves, the radiation from which forms the directive beam. This is established in each case by examining the role of the leaky waves in determining the near-field on the aperture of the structure and the far-field radiation pattern of the structure.

Abstract-A two dimensional periodic array of annular apertures (or ring slots) is studied using an accurate circuit model. The model accounts for distributed and dynamic effects associated with the excitation of high-order modes operating above or below cut-off but not far from their cut-off frequencies. This study allows to ascertain the substantial differences of the underlying physics when this structure operates as a classical frequency selective surface or in the extraordinary-transmission regime. A discussion of two different designs working at each regime is provided by means of the equivalent circuit approach, full wave simulation results, and experimental characterization. The agreement between the equivalent circuit calculation applied here and the simulation and experimental results is very good in all the considered cases. This validates the equivalent circuit approach as an efficient minimal-order model and a low computational-cost design tool for frequency selective surfaces and extraordinarytransmission based devices. Additional scenarios such as oblique incidence and parametric studies of the structural geometry are also considered.
