TL;DR: In this article, the results of theoretical analysis for guided modes in parallel-plate waveguides filled with pairs of parallel layers made of any two of the following materials are presented: (1) a material with negative real permittivity, but positive real permeability (epsilon-negative); (2) amaterial with negativereal permeability and positive real permitivity (mu-negative), and (3) a conventional material with both negative real and permeability, double-negative, in a given range of frequency.

TL;DR: In this paper, the authors introduced a pseudochiral medium for phase shifters, which is characterized electromagnetically by a set of bianisotropic constitutive relations and presented the physical insights into the coupling mechanism exhibited in such media.

TL;DR: A review of the available solutions for invisibility and cloaking that employ metamaterials and plasmonic materials at various frequencies can be found in this paper, where the main analogies and differences among these various approaches are discussed and some possible ideas for realizations and applications of these results are discussed.

TL;DR: In this article, the matching and radiation properties of subwavelength resonant patch antennas filled with double-negative, double-positive, and/or single-negative metamaterial blocks are analyzed.

TL;DR: It is demonstrated, using full-wave numerical simulations, how a homogeneous isotropic plasmonic material shell may basically "re-route" the impinging field in such a way to make dielectric and even conducting or metallic objects of a certain size nearly transparent to an outside observer placed in its near as well as in its far field.
