Magnetism from conductors and enhanced nonlinear phenomena
We show that microstructures built from nonmagnetic conducting sheets exhibit an effective magnetic permeability /spl mu//sub eff/, which can be tuned to values not accessible in naturally occurring…
Controlling Electromagnetic Fields
This work shows how electromagnetic fields can be redirected at will and proposes a design strategy that has relevance to exotic lens design and to the cloaking of objects from electromagnetic fields.
Metamaterial Electromagnetic Cloak at Microwave Frequencies
This work describes here the first practical realization of a cloak of invisibility, constructed with the use of artificially structured metamaterials, designed for operation over a band of microwave frequencies.
Mimicking Surface Plasmons with Structured Surfaces
It is established that electromagnetic waves in both materials are governed by an effective permittivity of the same plasma form, which allows the creation of designer surface plasmons with almost arbitrary dispersion in frequency and in space.
Low frequency plasmons in thin-wire structures
A photonic structure consisting of an extended 3D network of thin wires is shown to behave like a low density plasma of very heavy charged particles with a plasma frequency in the GHz range. We show…
Metamaterials and Negative Refractive Index
Recent advances in metamaterials research are described and the potential that these materials may hold for realizing new and seemingly exotic electromagnetic phenomena is discussed.
All-angle negative refraction without negative effective index
We describe an all-angle negative refraction effect that does not employ a negative effective index of refraction and involves photonic crystals. A few simple criteria sufficient to achieve this…
Surfaces with holes in them: new plasmonic metamaterials
In this paper we explore the existence of surface electromagnetic modes in corrugated surfaces of perfect conductors. We analyse two cases: one-dimensional arrays of grooves and two-dimensional…
A Chiral Route to Negative Refraction

The introduction of a single chiral resonance leads to negative refraction of one polarization, resulting in improved and simplified designs of negatively refracting materials and opening previously unknown avenues of investigation in this fast-growing subject.

Full electromagnetic simulations of the cylindrical version of this cloaking structure are reported, using ideal and nonideal electromagnetic parameters that show that the low-reflection and power-flow bending properties of the electromagnetic cloaky structure are not especially sensitive to modest permittivity and permeability variations.
