A recently published theory has suggested that a cloak of invisibility is in principle possible, at least over a narrow frequency band. We describe here the first practical realization of such a cloak; in our demonstration, a copper cylinder was “hidden” inside a cloak constructed according to the previous theoretical prescription. The cloak was constructed with the use of artificially structured metamaterials, designed for operation over a band of microwave frequencies. The cloak decreased… 
Low scattering microwave cloaking by all-dielectric metamaterials
The design of a cylindrical transmission cloak that provides low scattering cross width (SCW) at microwave frequencies is proposed. The cloak is composed of concentric layers of identical dielectric
Implementation of Low Scattering Microwave Cloaking by All-Dielectric Metamaterials
We present a cylindrical microwave cloak, which provides low total scattering cross width (TSCW) for cloaked objects larger than the wavelength. The cloak is composed of identical dielectric
Broadband electromagnetic cloaking of long cylindrical objects.
This Letter presents an experimental demonstration of cloaking for microwaves and simulation results for cloaking in the visible range and uses a simple structure made of metal layers to demonstrate a wideband and low-loss cloak.
In-band metamaterial cloak based on the interplay of absorption and transmission
A microwave metamaterial shelter with an electromagnetic narrow window over a broad absorption spectrum is experimentally demonstrated by resorting to conventional impedance-matching theory and
A Microwave Invisibility Cloak: The Design, Simulation, and Measurement of a Simple and Effective Frequency-Selective Surface-Based Mantle Cloak
In recent years, there has been a growing interest in developing invisibility cloaks that can conceal an object. These techniques are often based either on coating a dielectric or conducting object
Microwave cloaking by all-dielectric metamaterials
We present a cylindrical electromagnetic cloak composed of identical ceramic dielectric resonators for operation in the microwave range. The performance of the cloak has been verified by full-wave
Two-dimensional metamaterial structure exhibiting reduced visibility at 500 nm.
An experimental two-dimensional reduced visibility structure that approximates the distribution of the radial component of the dielectric permittivity necessary to achieve nonmagnetic cloaking in the visible frequency range is reported.
Three-dimensional broadband ground-plane cloak made of metamaterials
The first practical implementation of a fully 3D broadband and low-loss ground-plane cloak at microwave frequencies is realized, realized by drilling inhomogeneous holes in multi-layered dielectric plates.
A quasistatic magnetic cloak
Cloaking a three-dimensional object in free space from electromagnetic waves has recently become a theoretical possibility, although practical implementations can only be made in reduced schemes. If


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.
Spatial mapping of the internal and external electromagnetic fields of negative index metamaterials.
From the measured mappings of the electric field, the interplay between the microstructure of the metamaterial lattice and the macroscopic averaged response is revealed and the mapped phase fronts within a meetingamaterial having a negative refractive index are consistent with a Macroscopic phase-in accordance with the effective medium predictions.
General relativity in electrical engineering
In electrical engineering metamaterials have been developed that offer unprecedented control over electromagnetic fields. Here we show that general relativity lends the theoretical tools for
Free-space microwave focusing by a negative-index gradient lens
Metamaterial structures designed to have simultaneously negative permittivity and permeability are known as left-handed materials. Their complexity and our understanding of their properties have

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.

Here it is seen how a proper design of these lossless metamaterial covers near their plasma resonance may induce a dramatic drop in the scattering cross section, making these objects nearly "invisible" or "transparent" to an outside observer--a phenomenon with obvious applications for low-observability and noninvasive probe design.
Optical Conformal Mapping
A general recipe for the design of media that create perfect invisibility within the accuracy of geometrical optics is developed, which can be applied to escape detection by other electromagnetic waves or sound.
Refraction and geometry in Maxwell's equations
Computational studies of Maxwell's equations in complex geometries encountered in photonic band structure calculations run into difficulties when several length scales occur, such as the wavelength

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
Robust method to retrieve the constitutive effective parameters of metamaterials.
We propose an improved method to retrieve the effective constitutive parameters (permittivity and permeability) of a slab of metamaterial from the measurement of S parameters. Improvements over
