“…In particular, it may be a medium with negative permittivity or permeability. The negativity of permittivity takes place below the electron plasma frequency (the Drude formula) as the negativity of permeability taking place in the vicinity of the ferromagnetic resonance [5,6]. Now studies of different surface states attract attention of numerous research groups.…”

“…A detailed review for surface electromagnetic waves in one-dimensional periodic structure -photonic crystalcan be seen, e.g., [4][5][6][7][8]. In particular, a special feature of the surface Tamm states was emphasized there, i.e., the surface state appears when the wave vector of falling electromagnetic wave is normal to the interface boundary which separates the periodic medium from the medium with rapid attenuation of the wave.…”

Abstract-The paper is devoted to the study of microwave analogue of Tamm states appearing at the boundary of two different periodical chain-like structures in contact. A comparison of numerical and experimental data is provided for periodical chains of quadripoles modelling our system. As it turns out, at the point of contact of two different periodic structures, significant concentration of electromagnetic wave energy takes place. The corresponding concentration of energy is quite similar to those characteristics for Tamm states concentration which takes place at the boundary between two adjacent photonic crystals. We use the term microwave analogue of Tamm states for the considered periodic chain-like structures.

“…[11][12][13] A practical interest in SEMS has risen due to the fact that such states and the structures in which they are implemented can be used to create resonant optical filters, 14 polariton lasers, 15 and optical logic devices. 16 Up to date, a large number of theoretical and experimental studies of SEMS appearing at the interface between PM and PhC, 11,13,14,[17][18][19][20][21][22][23][24] as well as at the interface between two PhCs [11][12][13][25][26][27] have been carried out. In the gigahertz frequency range, SEMS at the interface between an artificial plasma-like media and PhC were, for the first time, experimentally investigated in Ref.…”

Frequencies of the surface electromagnetic states in the photonic crystal–ferrite–plasma-like medium structure were studied both theoretically and experimentally as a function of the ferrite layer thickness, external dc magnetic field and temperature. The photonic crystal was a periodic stack of a finite number of unit cells, each consisting of two different nonmagnetic dielectrics. A nonmagnetic semiconductor played the role of a plasma-like medium. A dc magnetic field was applied parallel to the ferrite layer. The propagation direction of an electromagnetic wave was perpendicular to the dc magnetic field with the electrical component of a microwave field parallel to the magnetic field. An analytical expression relating the frequencies of the surface electromagnetic states to the structural parameters and the magnitude of the dc magnetic field value was derived within the framework of the model of non-conducting and magnetized to saturation ferrite. It was predicted that the states under study are multimodal within a single photonic-crystal band gap.

The capabilities of perovskite-like compounds with the effect of colossal magnetoresistance (CMR) and some other complex oxides to have a negative index of refraction (NIR) are considered. Physical properties of these compounds are also analyzed from the standpoint of designing tunable metamaterials on their base. Of particular interest are temperature and magnetic field driven first-order transformations in oxides with perovskite structure and in spinels. These transformations give rise to nanophase separated states, using which the properties of negative refraction can be affected. The magnetic-field controlled metamaterials with CMR oxides as a boundary NIR media for a photonic crystal are discussed.
