The propagation of surface electromagnetic waves along photonic crystal (PC) boundaries is examined. It shown that in a number cases, these are backward waves. nature states localized at the PC boundary discussed; transfer no energy (their tangential wave zero). An analogy with well-known Tamm and Shockley solid state physics drawn. case PC, both types can be regarded as states. Experimental results on observation presented. A system using an external magnetic field to control considered.
We discuss phase transitions in $\mathcal{PT}$-symmetric optical systems. show that, due to frequency dispersion of the dielectric permittivity, an system can have $\mathcal{PT}$ symmetry at isolated points only. An assumption existence a continuous interval violates causality principle. Therefore, ideal symmetry-breaking transition cannot be observed by simply varying frequency.
We consider exciting surface plasmon polaritons in the Kretschmann configuration. Contrary to common belief, we show that a plane wave incident at an angle greater than of total internal reflection does not excite polaritons. These excitations do arise, however, if light forms narrow beam composed infinite number waves. The polariton is formed geometrical edge as result interference reflected
The mixing formulas for calculating the effective parameters of composite materials with inclusions having a negative permeability or permittivity are analyzed. problems appearing when various utilized were outlined, and computation algorithms yielding physically meaningful solutions described. problem calculation refractive index media arbitrary values is discussed.
We show that net amplification of surface plasmons is achieved in channel a metal plate due to nonradiative excitation by quantum dots. This makes possible lossless plasmon transmission lines the as well and generation coherent plasmons. As an example, ring spaser considered.
We demonstrate intracavity plasmonic laser spectroscopy using a created from periodically perforated silver film with liquid gain medium. An active zone of the is formed by highly elongated spot pumping. This results in significantly more efficient diffusive mixing dye molecules, which suppresses effect their bleaching, and ability to reduce volume medium as little 400 nl. use this design for stable multiple measurements that it effective spaser sensor detection an absorptive at 0.07 ppm....
In this paper we consider high frequency properties of composite materials. We use Monte Carlo simulations and Effective Medium Theory (EMT) to calculate the dielectric constant magnetic permeability. The EMT is a well-known approximation which used for describing conductivity, constant, permeability granular materials consisting conducting nonconducting components. Different modifications theory are considered when skin layer depth larger then characteristic size inclusions. microwave range...
In the approach to stationary regime, a surface plasmon amplification by stimulated emission of radiation exhibits complicated and highly nonlinear dynamics with anharmonic oscillations [M. I. Stockman, J. Opt. 12, 024004 (2010)]. We demonstrate that these are due Rabi quantum dot in field nanoparticle. show may or not arise depending on initial conditions.
Abstract We consider the transition from description of a closed quantum system consisting an open and reservoir to alone by eliminating degrees freedom averaging over them. An approach based on Lindblad master equation for density matrix is used. A general scheme developed deriving superoperator that emerges after von Neumann freedom. This illustrated with cases radiation two-level atom into free space dynamics pure state mixed due interaction dephasing reservoir. Special attention paid...
A comparative analysis of various forms the Maxwell equations for condensed matter is presented. It shown that so-called Casimir form contains enough information to solve any electromagnetic problem. The Landau–Lifshitz intended describing media with spatial dispersion requires an additional constitutive equation surface current, which does not set boundary condition but acts as a replacement usual Maxwell's continuity conditions tangential field components.

We propose an exactly solvable electrodynamical model for surface plasmon amplification by stimulated emission of radiation (spaser). The gain medium is described in terms the nonlinear permittivity with negative losses. demonstrates main feature a spaser: self-oscillating state (spasing) arising without external driving field if pumping exceeds some threshold value. In addition, it properly describes synchronization spaser within Arnold tongue and possibility compensating Joule losses when...

It is shown that spherical gain nanoparticle coated with metallic shell can operate as spaser amplifying circularly polarized surface plasmons. The may be used in design optical isolator transmission lines well spectrometry chiral molecules.
