“…15͒ as well as for the nonperiodic enhanced-transmission system discussed in this contribution. Our theory also matches the general point of view on this and other related topics reported in a recent review paper, 24 where the interaction of open resonators with plane waves is considered to be the essence of the phenomenon. GHz and almost total reflection ͑transmission level is about Ϫ32 dB͒ at 11.80 GHz.…”

This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics.This letter provides an experimental demonstration of extraordinary transmission in a closed waveguide system loaded with an electrically small diaphragm. This is a situation where the standard surface plasmon polariton SPP theory does not apply. The theoretical explanation is then based on the concept of impedance matching. This concept has previously been applied by some of the authors to account for enhanced transmission in situations where surface plasmon theory can be used: periodic arrays of small holes or slits in flat metal screens. The experiment in this letter supports the impedance matching model, valid for when SPPs are present or not. © 2009 American Institute of PhysicsThe authors would like to acknowledge the support of this research by the Spanish Ministry of Science and Innovation and European Union Feder Funds Grant Nos.

“…The first word, 'temporal', in the term [59] can be treated as historically coined. Essentially, the same method is employed to describe open resonators [60,61] and it goes back to the Lippmann and Schwinger's solution of the scattering problem in quantum mechanics [62]. This method is not to be confused with the theory of coupled waves [63][64][65], or the spatial theory of coupled modes widely used in the optics of cholesterics [27,[66][67][68][69].…”

Chiral Optical Tamm States: Temporal Coupled-Mode Theory

et al. 2017

Abstract:The chiral optical Tamm state (COTS) is a special localized state at the interface of a handedness-preserving mirror and a structurally chiral medium such as a cholesteric liquid crystal or a chiral sculptured thin film. The spectral behavior of COTS, observed as reflection resonances, is described by the temporal coupled-mode theory. Mode coupling is different for two circular light polarizations because COTS has a helical structure replicating that of the cholesteric. The mode coupling for co-handed circularly polarized light exponentially attenuates with the cholesteric layer thickness since the COTS frequency falls into the stop band. Cross-handed circularly polarized light freely goes through the cholesteric layer and can excite COTS when reflected from the handedness-preserving mirror. The coupling in this case is proportional to anisotropy of the cholesteric and theoretically only anisotropy in magnetic permittivity can ultimately cancel this coupling. These two couplings being equal result in a polarization crossover (the Kopp-Genack effect) for which a linear polarization is optimal to excite COTS. The corresponding cholesteric thickness and scattering matrix for COTS are generally described by simple expressions.

“…Thus, the analogy with plasmonics is not complete. Nevertheless, it is interesting to note that the bubble meta-screens are perfectly described by the unified description proposed by Bliokh et al [25], which is based on the open-resonator concept. Indeed, the bubble layer is an acoustic open resonator, with leakage and dissipative Q factors given by Q 1 leak = Ka and Q 1 diss = , respectively.…”
