“…SWs are typically nonradiative modes propagating along an interface with amplitudes that are evanescent in each bounding medium [11][12][13][14][15][16][17][18]. SWs have become a familiar physical concept in the optics and physics community thanks to the long-history investigation on surface plasmons, which are a kind of localized SWs that are typically excited in metal films.…”

Abstract-Existence of backward electromagnetic surface waves at an interface separating a semi-infinite uniform left-handed metamaterial and a 1D photonic crystal composed of alternating layers of two kinds of single-negative ( -negative and µ-negative) metamaterial is theoretically investigated. Dispersion characteristics of surface states are analyzed for two different cases of ENG-MNG and MNG-ENG layered periodic structures. It was demonstrated that in the presence of metamaterial, surface waves are sensitive to light polarization and there exist only backward TM-polarized (or TE-polarized) surface Tamm states depending on the ratio of the thicknesses of two periodic stacking layers.

“…Over the years, a large number of such and related problems have been solved [153][154][155][156][157][158][159][160]. The homogeneous material could be an isotropic dielectric material [153,155,157] or an anisotropic dielectric material [154,159], or even an isotropic NPV material [156,158,160]. Magnetic control is possible by the incorporation of gyrotropy in the relative permittivity dyadic of an anisotropic dielectric material [159].…”

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.

“…The low loss is a desirable property in SW applications because it leads to narrow coupling resonances and high surface-electromagnetic (EM) fields. Recently the linear SWs at the interface of a metamaterial and a semi-infinite 1DPC have been studied in the Reference [9] based on the transfer matrix method. Here, we study the properties of nonlinear type of SWs that can be excited at the interface between a uniform LH material and 1DPC capped by a nonlinear slab with finite thickness and we investigate a possibility to control the dispersion properties of SWs by adjusting the intensity of electromagnetic field.…”

Abstract-In this paper, the surface states (so called Tamm states) of a nonlinear self-focusing slab sandwiched between a uniform medium and a one-dimensional photonic crystal is investigated based on the first integral of the nonlinear Helmholtz wave equation. The considered slab can be a left-handed or a conventional material. It is shown that the structure can support the Tamm states with two different transverse electric structures. In one structure, the surface waves have one hump, and in the other one they have two humps at the surface of photonic crystal. We show that in the case of the self-focusing lefthanded metamaterial slab, there is a possibility to change the direction of the total energy flow of the surface waves by adjusting the intensity of exciting electromagnetic field.
