Materials with optical properties not found in the natural world can now be designed, offering unprecedented control over light and enhanced device functionality. 

Shaping optical space with metamaterials

By controlling the local electric and magnetic properties of a material, researchers can tailor the flow of light and create exotic optical devices.

Controlling birefringence in dielectrics

Using transformation optics, researchers predict that birefringent dielectrics can be engineered to control both polarizations of light independently. They also show that structures can be designed

Trapping light by mimicking gravitational lensing

We propose a distorted optical waveguide around a microsphere to mimic curved spacetimes caused by the “gravitational fields”. Gravitational lensing effects analogues are experimentally demonstrated

Transformation optics and metamaterials.

The potential of transformation optics to create functionalities in which the optical properties can be designed almost at will is reviewed, which can be used to engineer various optical illusion effects, such as the invisibility cloak.

Conformal transformation optics

Transformation optics is a modern application of Maxwell's equations offering unprecedented control over the flow of light that exploits spatially customized optical properties and mathematical

Evidence for subwavelength imaging with positive refraction

The resolution of lenses is normally limited by the wave nature of light. Imaging with perfect resolution was believed to rely on negative refraction, but here we present experimental evidence for

Transforming light and sound with metamaterials

In this invited talk, we present the fabrication and characterization of optical and acoustic metamaterials, incorporating unique topological interactions between waves and matter. We propose

Partial transmutation of singularities in optical instruments

Some interesting optical instruments such as the Eaton lens and the invisible sphere require singularities of the refractive index for their implementation. We show how to transmute those

Manipulating Complex Light with Metamaterials

It is shown how unique properties of MMs, namely the ability to manipulate both electric and magnetic field components of electromagnetic (EM) waves, open new degrees of freedom in engineering complex polarization states of light at will, while preserving its orbital angular momentum (OAM) state.

Broadband phase-preserved optical elevator

Phase-preserved optical elevator is an optical device to lift up an entire plane virtually without distortion in light path or phase. Using transformation optics, we have predicted and observed the



Optics: Beyond diffraction

A material with a cunningly designed optical response overcomes a fundamental limit to image resolution. This 'hyperlens' produces magnified images of objects smaller than the wavelength of the

Optical Hyperlens: Far-field imaging beyond the diffraction limit.

We propose an approach to far-field optical imaging beyond the diffraction limit. The proposed system allows image magnification, is robust with respect to material losses and can be fabricated by

Impedance matched hyperlens

An imaging system capable of magnification, subwavelength-resolution and impedance matching, which minimizes reflection losses is developed, which is based on available materials and existing fabrication technologies.

Magnifying Superlens in the Visible Frequency Range

A magnifying superlens that can be integrated into a conventional far-field optical microscope, based on a multilayer photonic metamaterial consisting of alternating layers of positive and negative refractive index, is demonstrated.

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.

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.

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.

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

On cloaking for elasticity and physical equations with a transformation invariant form

In this paper, we investigate how the form of the conventional elastodynamic equations changes under curvilinear transformations. The equations get mapped to a more general form in which the density
