Emitting and negatively-refractive focusing apparatus, methods, and systems

TL;DR: In this paper, the authors provide an overview of methods and systems for both emitting and negatively-refractive focusing of electromagnetic energy, where the transformation medium may include an artificially-structured material such as a metamaterial.
Journal ArticleDOI

Modeling and observation of mid-infrared nonlocality in effective epsilon-near-zero ultranarrow coaxial apertures.

TL;DR: In this article, the authors examined non-local optical effects in small gaps and its effect on the optical response of a coaxial metamaterial in the mid-IR, including spectral shifts and boosted transmittance of the cutoff epsilon-near zero mode.
Journal ArticleDOI

Partial focusing by indefinite complementary metamaterials

TL;DR: In this paper, a two-dimensional partial focusing within a planar waveguide using complementary indefinite metamaterials was realized using complementary electric resonator (CELC) structures.

Surface scattering antenna array

TL;DR: In this paper, an array of scattering and/or reflector antennas are configured to produce a series of beam patterns, where in some embodiments the scattering antenna and or the reflector antenna includes complementary metamaterial elements.
Journal ArticleDOI

Experimental determination of the quadratic nonlinear magnetic susceptibility of a varactor-loaded split ring resonator metamaterial

TL;DR: In this paper, the second harmonic generated by a slab of varactor loaded split ring resonator metamaterial and the retrieval of the effective quadratic nonlinear magnetic susceptibility χm(2) using an approach based on transfer matrices was presented.
