The possibility of cloaking an object from detection by electromagnetic waves has recently become a topic of considerable interest. The design of a cloak uses transformation optics, in which a conformal coordinate transformation is applied to Maxwell's equations to obtain a spatially distributed set of constitutive parameters that define the cloak. Here, we present an experimental realization of a cloak design that conceals a perturbation on a flat conducting plane, under which an object can be… 

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.

Cloaking at Optical Frequencies

2 The ability of rendering objects invisible using a cloak – not detectable by an external observer – for concealing objects has been a tantalizing goal 1-6. Here, we demonstrate a cloak operating in

The idea of cloaking objects from the observation by electromagnetic (EM) fields based on the recently proposed transformation optics requires anisotropic space-dependent inhomogeneous medium to

Wideband performance analysis of ground-plane cloak designed with polarization-independent randomly patterned metamaterial

A ground-plane cloak is designed based on the quasi-conformal mapping method to hide a perfectly conducting object, fabricated with a metamaterial, a mixture of a dielectric and air, to guarantee the statistical isotropy of the cloak structure.

On the Sensitivity of Practical Electromagnetic Ground Plane Cloaks

A numerical study of the sensitivity of the two dimensional electromagnetic ground plane cloak in the visible spectrum is performed using the finite difference time domain method. Transverse magnetic

An optical cloak made of dielectrics.

The optical 'carpet' cloak is designed using quasi-conformal mapping to conceal an object that is placed under a curved reflecting surface by imitating the reflection of a flat surface and enables broadband and low-loss invisibility at a wavelength range of 1,400-1,800 nm.

Rendering an object invisible through a cloaking device is an ongoing dream of human beings and material scientists. Recently, intensive theories and experiments have predicted and demonstrated that

We present a scheme to realize a broadband antenna which is hidden under the ground but still possesses radiating performance with steerable beams as its free-space counterpart. This antenna is made

Experimental Realization of an Extreme-Parameter Omnidirectional Cloak

This work reports on the first experimental demonstration of an omnidirectional cloak that satisfies the extreme parameters requirement, which can hide objects in a homogenous background using a nonresonant metamaterial comprising arrays of subwavelength metallic channels manufactured with 3D metal printing technology.

Simplified ground plane invisibility cloak by multilayer dielectrics.

An alternative method to design the ground plane invisibility clock with electromagnetic beam modulation blocks through simple coordinate transformation discussed in the previous work is proposed and can leads to easy experimental demonstration of non-magnetic ground plane cloak in the frequency range from microwave to optical.



Optical cloaking with metamaterials

This work presents the design of a non-magnetic cloak operating at optical frequencies, and the principle and structure of the proposed cylindrical cloak are analysed and the general recipe for the implementation of such a device is provided.

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.

Electromagnetic wave interactions with a metamaterial cloak.

We establish analytically the interactions of electromagnetic wave with a general class of spherical cloaks based on a full wave Mie scattering model. We show that for an ideal cloak the total

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.

Electromagnetic parameter retrieval from inhomogeneous metamaterials.

It is shown here that a modification of the standard S-parameter retrieval procedure yields physically reasonable values for the retrieved electromagnetic parameters, even when there is significant inhomogeneity within the unit cell of the structure.
