“…In 2008, Smolyaninov et al achieved a noticeable reduction in the scattering of SPPs incident upon a cloak consisting of polymethylmethacrylate (PMMA) at a wavelength of 532 nm [19,20] . More recently, Baumeier et al demonstrated theoretically that it is possible to reduce signifi cantly the scattering of an object by an SPP at a wavelength of 633 nm when it is surrounded by two concentric rings of point scatterers [21] .…”

Surface plasmons polaritons (SPPs) at metal/dielectric interfaces have raised lots of expectations in the on-going quest towards scaling down optical devices. SPP optics offers a powerful and fl exible platform for real two-dimensional integrated optics, capable of supporting both light and electrons. Yet, a full exploitation of the features of SPPs is conditioned by an accurate control of their fl ow. Most efforts have so far focused on the extrapolation of concepts borrowed from guided optics. This strategy has already led to many important breakthroughs but a fully deterministic control of SPP modes remains a challenge. Recently, the fi eld of optics was stimulated by a novel paradigm, transformation optics, which offers the capability to control light fl ow in any desired fashion. While it has already signifi cantly contributed to the design of metamaterials with unprecedented optical properties, its versatility offers new opportunities towards a fully deterministic control of SPPs and the design of a new class of plasmonic functionalities. Here, we review recent progress in the application of transformation optics to SPPs. We fi rst briefl y describe the theoretical formalism of transformation plasmonics , focusing on its specifi cities over its three-dimensional optical counterpart. Numerical simulations are then used to illustrate its capability to tame SPP fl ows at a metal interface patterned with a dielectric load. Finally, we review recent experimental implementations leading to unique SPP functionalities at optical frequencies.

“…4]. The practical interest in devising the cloaking devices is no longer confined to the electromagnetic waves [62][63][64][65][66][67][68][69][70][71][72], but has also imbued the similar quest related with the acoustic waves [73][74][75][76][77][78][79][80][81][82][83][84][85] and the plasmonic waves [86][87][88][89][90][91][92][93][94][95][96][97][98]. The cloakmania has gone to the extent that some scientists think that all the attention paid to cloaking phenomenon distracts us from the technology's true potential: anything that makes use of the electromagnetic spectrum might be improved or altered!…”

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...

Abstract-Leaky-wave radiations are usually generated by leaking the electromagnetic energy gradually over a structure. By using the coupling effect and leaky-wave properties, this paper designs a novel 1-D frequency scanning antenna array. The antenna is intended for the direct imaging radar sensors. The simulated results show that the scanning angle can stay in the range from −60 • to 30 • . The proposed 1-D antenna array was manufactured, and the measured results are consistent with the simulated ones.
