“…Here, it should be noted that our expressions for the total cross sections σ H T (ω) and σ E T (ω) are different from the expressions given by Kuzmiak and Maradudin 11 . It seems to us that these authors have incorrectly applied the boundary conditions for the electric and magnetic fields at the cylinder surface.…”

Surface polaritons on left-handed cylinders: A complex angular momentum analysis

et al. 2005

We consider the scattering of electromagnetic waves by a left-handed cylinder -i.e., by a cylinder fabricated from a left-handed material -in the framework of complex angular momentum techniques. We discuss both the TE and TM theories. We emphasize more particularly the resonant aspects of the problem linked to the existence of surface polaritons. We prove that the long-lived resonant modes can be classified into distinct families, each family being generated by one surface polariton propagating close to the cylinder surface and we physically describe all the surface polaritons by providing, for each one, its dispersion relation and its damping. This can be realized by noting that each surface polariton corresponds to a particular Regge pole of the S matrix of the cylinder. Moreover, for both polarizations, we find that there exists a particular surface polariton which corresponds, in the large-radius limit, to the surface polariton which is supported by the plane interface. There exists also an infinite family of surface polaritons of whispering-gallery type which have no analogs in the plane interface case and which are specific to left-handed materials.

“…Interestingly, while the excitation of propagating surface plasmon polaritons in μ < 0 and left-handed toy-model materials has been studied [4,[9][10][11][12] (some of these works explicitly stating the symmetry relations between these and their analog in conventional ε < 0 metals [11,12]), very few works deal with the localized version of these collective modes [13] in realistic scenarios. In fact, most of the studies related to scattering from bodies with μ < 0 consider simultaneously ε < 0, thus being left-handed [14][15][16][17][18]. In recent years, the fact that the lowest-order resonance found in the extinction spectrum of (realistic) high-refractive-index spheres/rings typically presents a definite dipolar magnetic character has been exploited to achieve magnetic dipole response with single particles made of nonmagnetic materials [19][20][21][22][23][24][25][26][27].…”

Localized magnetic plasmons in all-dielectricμ<0metastructures

et al. 2015

Metamaterials are known to exhibit a variety of electromagnetic properties nonexisting in nature. We show that an all-dielectric (nonmagnetic) system consisting of deep-subwavelength, high-permittivity resonant spheres possesses effective negative magnetic permeability (dielectric permittivity being positive and small). Due to the symmetry of the electromagnetic wave equations in classical electrodynamics, localized "magnetic" plasmon resonances can be excited in a metasphere made of such metamaterial. This is theoretically demonstrated by the coupled-dipole approximation and numerically for real spheres, in full agreement with the exact analytical solution for the scattering process by the same metasphere with effective material properties predicted by effective medium theory. The emergence of this phenomenon as a function of structural order within the metastructures is also studied. Universal conditions enabling effective negative magnetic permeability relate subwavelength sphere permittivity and size with critical filling fraction. Our proposal paves the way towards (all-dielectric) magnetic plasmonics, with a wealth of fascinating applications.

“…Photons are emitted as an insulator's electrons restore themselves to the ground state after the disruption has passed. A reverse Cherenkov effect can be experienced using the NIMs: this means that when a charged particle passes through a (metamaterial) medium at a speed greater than the speed of light in that medium, that particle will radiate from a cone behind itself [see The subject of metamaterials, or (artificially) engineered composites, has gained un unexpected momentum and the research interest seems to have focused not only on the photonic crystals with metamaterial components [26][27][28][29][30][31][32][33] but also on the single-and multi-layered planar structures [34][35][36][37][38][39][40][41][42][43] as well as on the (usually) single cylindrical geometries [44][45][46][47][48][49][50][51][52][53][54][55]. The interesting phenomena emerging from the geometries involving metamaterials include the slowing, trapping, and releasing of the light signals [56], the proposal of the cloaking devices [57], and the extraordinary refraction of light [58] (see Fig.…”

Thanks to Victor Veselago for his hypothesis of negative index of refraction, metamaterials -engineered composites -can be designed to have properties difficult or impossible to find in nature: they can have both electrical permitivity (ǫ) and magnetic permeability (µ) simultaneously negative. The metamaterials -henceforth negative-index materials (NIMs) -owe their properties to subwavelength structure rather than to their chemical composition. The tailored electromagnetic response of the NIMs has had a dramatic impact on the classical optics: they are becoming known to have changed many basic notions related with the electromagnetism. The present article is focused on gathering and reviewing the fundamental characteristics of plasmon propagation in the coaxial cables fabricated of the right-handed medium (RHM) [with ǫ > 0, µ > 0] and the left-handed medium (LHM) [with ǫ < 0, µ < 0] in alternate shells starting from the innermost cable. Such structures as conceived here may pave the way to some interesting effects in relation to, e.g., the optical science exploiting the cylindrical symmetry of the coaxial waveguides that make it possible to perform all major functions of an optical fiber communication system in which the light is born, manipulated, and transmitted without ever leaving the fiber environment, with precise control over the polarization rotation and pulse broadening. The review also covers briefly the nomenclature, classification, potential applications, and the limitations (related, e.g., to the inherent losses) of the NIMs and their impact on the classical electrodynamics, in general, and in designing the cloaking devices, in particular. Recent surge in efforts on invisibility and the cloaking devices seems to have spoiled the researchers worldwide: proposals include not only a way to hide an object without having to wrap the cloak around it, but also to replace a given object with another, thus adding to the deception even further! All this is attributed as much to the fundamental as to the practical advances made in the fabrication and characterization of NIMs. The report concludes addressing briefly the anticipated implications of plasmon observation in the multicoaxial cables and suggesting future dimensions worth adding to the problem. The background provided is believed to make less formidable the task of future writers of reviews in this field. The civilization of the ancient Greeks, Hindus, and Romans has been immensely influential on the art, education, architecture, language, politics, philosophy, science, and technology of the modern world: from the surviving fragments of classical antiquity until the Renaissance in Western Europe. While descriptions of disciplined empirical scientific methods have been employed since the Middle Ages, the dawn of modern science is generally traced back to the early modern period during what is known as the Scientific Revolution of the 16th and 17th centuries. From the Middle Ages to the Enlightenment, the preferred term for the study of nature a...
