“…The main drawback of such a technique is the extreme sensitivity of plasmonic resonances to material losses. We also mention that similar cloaking effects at a distance outside the cloaking shell can be induced using complementary media like pairs of right handed and left handed media [177,178].…”

Abstract-Invisibility has been a tantalizing concept for mankind over several centuries. With recent developments in metamaterial science and nanotechnology, the possibility of cloaking objects to incoming electromagnetic radiation has been escaping the realm of science fiction to become a technological reality. In this article, we review the state-of-the-art in the science of invisibility for electromagnetic waves, and examine the different available technical concepts and experimental investigations, focusing on the underlying physics and the basic scientific concepts. We discuss the available cloaking methods, including transformation optics, plasmonic and mantle cloaking, transmission-line networks, parallel-plate cloaking, anomalous resonance methods, hybrid methods and active schemes, and give our perspective on the subject and its future. We also draw a parallel with cloaking research for acoustic and elastodynamic waves, liquid waves, matter waves and thermal flux, demonstrating how ideas initiated in the field of electromagnetism have been able to open groundbreaking venues in a variety of other scientific fields. Finally, applications of cloaking to noninvasive sensing are discussed and reviewed.

“…Using transformation optics, we design an illusion device consisting of two distinct pieces of metamaterials, which are called the "complementary medium" and the "restoring medium". The complementary medium concept, which was first proposed by Pendry et al to make focusing lenses [28,29], is applied here to "cancel" a piece of space optically, including the object [21,22].…”

“…Recently, we proposed an approach to realize "cloaking at a distance" by using an "anti-object" [21,22]. Here, by combining the "anti-object" cloaking functionality and the image projection functionality, we achieve a general form of illusion optics such that an object can be disguised into something else and the illusion device itself is invisible.…”

Illusion Optics: The Optical Transformation of an Object into Another Object

We propose to use transformation optics to generate a general illusion such that an arbitrary object appears to be like some other object of our choice. This is achieved by using a remote device that transforms the scattered light outside a virtual boundary into that of the object chosen for the illusion, regardless of the profile of the incident wave.This type of illusion device also enables people to see through walls. Our work extends the concept of cloaking as a special form of illusion to the wider realm of illusion optics.

“…Besides the light-bending transformation optics approach, there exist other ways to realize cloaking [20][21][22][23][24][25][26][27][28][29][30][31][32]. Even before transformation optics, it has been proposed that by making a plasmonic coating on a particle, the scattering cross section of the particle can be reduced dramatically [20], achieving a cloaking effect.…”

The technique of "transformation optics" establishes a correspondence between coordinate transformation and material constitutive parameters. Most of the transformation optics mappings give metamaterials that have graded positive refractive indices that can steer light in curves defined by the coordinate transformation. We will focus on those "folded-geometry mappings" that give negative refractive index materials that have special wave scattering properties. One interesting example is a kind of remote illusion device that can transform the stereoscopic image of an object into the illusion of some other object of our choice. The conceptual device can create the illusion without touching or encircling the object. For any incident wave, the device transforms the scattered waves of the original object into that of the object chosen for illusion outside a virtual boundary. We will illustrate some possible applications of this type of metamaterial remote device, including "cloaking at a distance," partial cloaking, cloaking from an embedded device, revealing a hidden object inside a container, turning the image of one object into that of another object, and seeing through a wall. The feasibility of building this remote illusion device by metamaterials will also be discussed.
