“…The structure is set so that it is weakly guiding as discussed in section 2 of [120]. When part of the structure (as shown in figure 24), in the form of the substrate, is replaced with a magnetooptic material, it is possible to control solitons with the application of a magnetic field.…”

“…The form of the extended NLSE is given below in equation (6.1) and is as discussed in equation (2.22) of [120]. It is noted that there is also the capability of adding higher order and Raman scattering effects however in the simulations discussed below these parameters are not invoked, but will be utilised in future work.…”

“…Subsequently in order to consider metamaterial effects the parameters that are adjusted here are as given above (see also [120]), which are: S the self-steepening coefficient, t ν the delay of the magnetisation after excitation by the electromagnetic input, Δt ν the normalised time over which the magnetisation takes place, v g the group velocity and ν max , the maximum value of magnetisation Having established the Peregrine solution the next step is to introduce self-steepening. The self-steepening can be negative or positive, and it is shown that it is possible to arrange for the peak of the Peregrine to appear in different time slots depending on the values selected for the self-steepening coefficient.…”

Waves in hyperbolic and double negative metamaterials including rogues and solitons

The topics here deal with some current progress in electromagnetic wave propagation in a family of substances known as metamaterials. To begin with, it is discussed how a pulse can develop a leading edge that steepens and it is emphasised that such self-steepening is an important inclusion within a metamaterial environment together with Raman scattering and third-order dispersion whenever very short pulses are being investigated. It is emphasised that the self-steepening parameter is highly metamaterial-driven compared to Raman scattering, which is associated with a coefficient of the same form whether a normal positive phase, or a metamaterial waveguide is the vehicle for any soliton propagation. It is also shown that the influence of magnetooptics provides a beautiful and important control mechanism for metamaterial devices and that, in the future, this feature will have a significant impact upon the design of data control systems for optical computing. A major objective is fulfiled by the investigations of the fascinating properties of hyperbolic media that exhibit asymmetry of supported modes due to the tilt of optical axes. This is a topic that really merits elaboration because structural and optical asymmetry in optical components that end up manipulating electromagnetic waves is now the foundation of how to operate some of the most successful devices in photonics and electronics. It is pointed out, in this context, that graphene is one of the most famous plasmonic media with very low losses. It is a two-dimensional material that makes the implementation of an effectivemedium approximation more feasible. Nonlinear non-stationary diffraction in active planar anisotropic hyperbolic metamaterials is discussed in detail and two approaches are compared. One of them is based on the averaging over a unit cell, while the other one does not include sort of averaging. The formation and propagation of optical spatial solitons in hyperbolic metamaterials is also considered with a model of the response of hyperbolic metamaterials in terms of the homogenisation ('effective medium') approach. The model has a macroscopic dielectric tensor encompassing at least one negative eigenvalue. It is shown that light propagating in the presence of hyperbolic dispersion undergoes negative (anomalous) diffraction. The theory is ten broadened out to include the influence of the orientation of the optical axis with respect to the propagation wave vector.

It is strongly discussed that metamaterials and optical rogue waves have both been making headlines in recent years and that they are, separately, large areas of research to study.

Abstract. In this paper we develop a new method for the analysis of excitation and propagation of planetary electromagnetic waves (PEMW) in the ionosphere of the Earth. The nonlinear system of equations for PEMW, valid for any height, from D to F regions, including intermediate altitudes between D and E and between E and F regions, is derived. In particular, we have found the system of nonlinear one-fluid MHD equations in the β-plane approximation valid for the ionospheric F region (Aburjania et al., 2003a(Aburjania et al., , 2005. The series expansion in a "small" (relative to the local geomagnetic field) non-stationary magnetic field has been applied only at the last step of the derivation of the equations. The small mechanical vertical displacement of the media is taken into account. We have shown that obtained equations can be reduced to the well-known system with Larichev-Reznik vortex solution in the equatorial region (see e.g. Aburjania et al., 2002). The excitation of planetary electromagnetic waves by different initial perturbations has been investigated numerically. Some means for the PEMW detection and data processing are discussed.

Plasmonics has been attracting considerable interest as it allows localization of light at nanoscale dimensions. A breakthrough in integrated nanophotonics can be obtained by fabricating plasmonic functional materials. In particular, magneto‐optical materials are appealing as they may provide ultrafast control of laser light and surface plasmons via an external magnetic field. In this article, we demonstrate that it provides a significant enhancement of magneto‐optical effects as proved by increase in the intensity and polarization rotation effects by several orders of magnitude. Plasmonic structures can be operated in transmission, so that it may be implemented in devices for telecommunication, plasmonic circuitry, magnetic field sensing, and all‐optical magnetic data storage.
