“…The dashed lines correspond to the k dependent edges of the non-Bragg gap, and the dotted lines give the dispersion relation of the branches of the electromagnetic modes arising in the bulk metamaterial of the superconductor parameter Λ in the range of values 0 ≤ kd/π ≤ 1 there is only one mode in case (a), and two modes in case (b), with a low-frequency mode which arises from the low-frequency continuum of the bulk metamaterial modes at a non-zero in-plane wave vector k. Such behavior is similar to that shown for Tamm states in semiconductor superlattices with two-dimensional electron gas [14,15].…”

Transmission coefficient and dispersion relation are calculated for a one-dimensional photonic crystal of alternating dielectric-metamaterial slabs with a dielectricsuperconductor pair defect. The presence of the superconductor slab in the pair defect layer leads to a strong depletion of the TM transmission coefficient in a frequency range close to the edges of the non-Bragg gap and around the characteristic resonance frequency of the superconductor and introduces TM electromagnetic modes inside such gap. The features of the arising modes depend on the relation between the thicknesses of the layers involved in the defect and a low-frequency mode can arise from the lowfrequency continuum of the bulk metamaterial modes at a non-zero in-plane wave vector.

“…Due to the translation invariance of the system structures considered here in the x y plane, therefore, only two components of wavevectors are necessary in the solutions. Consequently, the non-zero components of the electric fields in the three regions can be written as follows [20,23,24]:…”

“…The occurrence of surface plasmon modes significantly relies on the ratio of the dielectric constants of the two materials. The localized interface plasmon modes (IPMs) in a system composed of two semi-infinite semiconductor superlattices separated by a space of d have also been explored [20]. Two branches consisting of higher-energy and lower-energy IPMs are found arising from symmetric or antisymmetric linear combinations of plasmon eigenstates of the prototype perfect superlattices.…”

We study the properties of the localized interface plasmon modes (IPMs) arising from coupling and splitting of the plasmon eigenstates in two semiinfinite superlattices containing complex defect structures. Two kinds of defect structure are considered: one is a single quantum well, i.e., a barrier-wellbarrier structure; the other is a well-barrier-well structure. The influences of the constitution of the defect structures, as well as the physical and geometric parameters of the superlattices on the characteristics of the localized IPMs are investigated in detail. The numerical results show that the localized modes exhibit peculiar features; the complexity of the dispersion of IPMs is essentially associated with the coupling of the interwell regions in the defect structure, and the barrier and well layers play different roles in the features of the localized IPMs. We also present a comparison of the dispersions of the localized IPMs between these two types of defect structure and give a physical picture to explain these results.

“…The extension of these works to the case of applied magnetic fields was discussed by Kushwaha [25]. Recently much attention has been paid to the description of the local modes related with the removal of translational symmetry, as for a superlattice with a defect layer [13,26] or a superlattice with a quasiperiodic region following Fibonacci [27] or Cantor [28] sequences. The effects of an applied external magnetic field have also been considered using Green's function techniques [14,30].…”

The electromagnetic propagator associated with the localized collective magnetoplasmon excitations in a semiconductor superlattice with broken translational symmetry, is calculated analytically within linear response theory. We discuss the properties of these collective excitations in both radiative and nonradiative regimes of the electromagnetic spectra. We find that low frequency retarded modes arise when the surface density of carriers η d at the symmetry breaking layer is lower than the density η 0 at the remaining layers. Otherwise (η d > η 0 ) a doublet of localized, high-frequency magnetoplasmon-like modes occurs. The corresponding dispersion law and power spectrum of these modes are shown.
