We predict a new branch of surface Josephson plasma waves (SJPWs) in layered superconductors for frequencies higher than the frequency. In this frequency range, permittivity tensor components along and transverse to layers have different signs, which is usually associated with negative refraction. However, these frequencies, bulk cannot be matched incident reflected vacuum, and, instead negative-refractive properties, abnormal modes appear within band expected modes. also discuss excitation...

We discuss the propagation of symmetric and antisymmetric Josephson plasma waves in a slab layered superconductor clad between two identical dielectrics. predict branches surface terahertz frequency range, one above another below frequency. Apart from this, there exists discrete set waveguide modes with electromagnetic fields oscillating across thickness decaying exponentially away slab. consider excitation predicted by means attenuated-total-reflection method. It is shown that for specific...

We predict the enhanced transmissivity of modulated slabs layered superconductors for terahertz radiation due to diffraction incident wave and resonance excitation eigenmodes. The electromagnetic field is transferred from irradiated side a slab superconductor other one by excited waveguide modes (WGMs) which do not decay deep into slab, contrary metals, where light transmission caused evanescent surface waves. show that series peaks (with $T \sim 1$) can be observed in dependence...

We analytically study the excitation of surface Josephson plasma waves (SJPWs) propagating across junctions in layered superconductors presence external dc magnetic field. Both attenuated total reflection and modulation superconducting parameters methods SJPWs are considered. show that incident electromagnetic wave can be substantially decreased due to resonance SJPWs, for certain angles frequencies when changing Moreover, we find physical conditions guaranteeing suppression specular...

We consider here a layered superconductor subject to an externally applied moderately strong electromagnetic field. predict hysteretic jumps in the dependence of surface reactance on amplitude ${H}_{0}$ incident wave. This very unusual nonlinear phenomenon can be observed thin superconducting slabs at not ac amplitudes if frequency irradiating field is close Josephson plasma frequency. Using set coupled sine-Gordon equations, we derive expression for phase shift $\ensuremath{\chi}$ reflected...

A reduction in the transmission of terahertz radiation through a periodically modulated slab layered superconductor owing to diffraction incident wave and resonance excitation eigenmodes is predicted studied theoretically. The thickness assumed be much less than skin depth when there no modulation close unity.

The nonlinear response of a layered superconductor to symmetric (in magnetic field) electromagnetic excitation has been theoretically investigated. An ambiguous dependence the phase reflected signal on amplitude H0 irradiating wave is predicted. This causes hysteresis jumps in surface reactance H0. If frequency field close Josephson plasma frequency, this unusual effect can be observed when amplitudes ac are not very strong. conditions for appearance obtained. Expressions shift derived,...

The quantum diffusion in a one-dimensional lattice tunneling regime under the influence of spatially inhomogeneous Gaussian noise is studied theoretically. It shown that thermopower appears at an arbitrary value coupling. In strong extremely high temperature, when drift component charge transport can be neglected, thermoelectric effect takes place only presence constant external electric field. Seebeck and Peltier coefficients for closed-circuit mode are obtained medium regime. regime, both...

Weakly nonlinear localized electromagnetic modes in a slab of layered superconductor are investigated theoretically. It is assumed that the located homogeneous dielectric environment, superconducting layers oriented perpendicular to surface and propagate across layers. Owing strong anisotropy Josephson plasma superconductors, can show unusual dispersion properties. The field determined by distribution gauge-invariant phase difference order parameter satisfies set coupled sine-Gordon...

In this review, the propagation of electromagnetic waves localized near boundary a layered superconductor sample with layers either parallel or perpendicular to its surface is discussed. The results obtained in series studies on investigating dispersion relation for such are generalized, classified and supplemented. Because strong anisotropy nonlinearity Josephson plasma superconductors can possess unusual resonance properties, their excitation be accompanied by specific phenomena. field...
