“…Many structures such as slab waveguides and planar multilayered structures are important in the development of surface-wave devices [33][34][35][36][37][38]. Although such structures have been and are the focus of many investigations, our attention here is confined to guidance by a single interface.…”

From the beginning of the 20th century, researchers have been interested in surface electromagnetic waves guided by planar interfaces of dissimilar mediums. Much initial research on surface-plasmon waves and surface-plasmonpolariton waves stemmed from theoretical curiosity, but the development of new experimental techniques propelled commercial exploitation for optical sensors of chemical and biological species. Additional surface waves called Dyakonov waves, Tamm waves, and Dyakonov-Tamm waves have emerged during the last 25 years. Experimental observation of Dyakonov waves was reported only in 2009, but the rapid development of experimental apparatus during the 1990s suggests that theoretical predictions will soon be evaluated experimentally, leading to further development of optical detection systems and optical circuitry.

“…Previous studies on the modes of structures involving anisotropic media include [11±13] (at a single interface), [14] (the same con®guration as studied here, except that the optic axis of the crystal belongs to the interface, thus excluding double resonances), [15,16] (guided waves in anisotropic media), [17] (two ®lms), [18] (the same structure as considered here, but the study therein does not include double excitations), [19] (®rst observation of enhanced optical secondharmonic generation due to excitation of long-range surface plasmons at a multilayer structure), [20] (multilayered structure, but for a particular orientation of the principal dielectric tensor axes of the anisotropic layer), [21,22] (guided modes in a liquid-crystal layer and surface plasmon resonance in a metal-clad liquid-crystal waveguide respectively), [23,24] (excitation of surface modes at a single uniaxial crystal±metal interface) and [25±28] (examples of excitation at anisotropic gratings). Here we obtain the complex propagation constants of the eigenmodes supported by the uniaxial crystal±metal±isotropic medium ®lm and show the existence of a set of critical ®lm parameters for which the excitation is linked to zeros of the re¯ected power.…”

We perform a theoretical study about the interaction between light and the eigenmodes of a metallic ®lm that separates a uniaxial crystal from an isotropic medium. These structures support two di erent eigenmodes: a surface mode at the isotropic medium±metal interface and another mode at the crystal±metal interface. We show that, contrary to what happens in isotropic con®gurations, these two modes can couple to incident radiation without corrugating the surface or adding another interface. We give conditions to obtain zero re¯ected power and a strong enhancement of the ®elds at both interfaces. We also show that, owing to the di erent characteristics of the modes supported by each interface, the relative position of their propagation constants in the complex plane can be selected rather arbitrarily by tuning the ®lm parameters. We give examples in which both couplings occur for angles of incidence either very di erent (separate resonances) or very close (almost double resonances). In the latter case we observe the phenomenon of`reluctance' between resonances.

“…The results hold for different geometries, including antiguiding structures. 13 The concept put forward is important in that it might permit the observation of Dyakonov resonances; it might find applications also in the characterization of nanolayers of chemical and biological materials with magnetic properties, [14][15][16][17]…”

We address the existence and properties of lossless surface waves that form at interfaces between magnetic and birefringent media. We show that the angular domain of existence of Dyakonov surface waves for magnetic interfaces is significantly larger than that for nonmagnetic ones. Our results have important implications for the experimental generation of surface waves and for their potential applications based on guided-to-leaky transitions.
