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…

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.

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.

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.
