We study the behavior of wave propagation in materials for which not all of the principal
elements of the permeability and permittivity tensors have the same sign. We find that a wide …

Metamaterials is a young subject born in the 21st century. It is concerned with artificial
materials which can have electrical and magnetic properties difficult or impossible to find in …

In the past few years, new developments in structured electromagnetic materials have given
rise to negative refractive index materials which have both negative dielectric permittivity …

Materials that can bend light in the opposite direction to normal ('left-handed'materials)
reverse the way in which refraction usually works—this negative refractive index is due to …

We experimentally and theoretically demonstrate single-beam negative refraction and
superlensing in the valence band of a two-dimensional photonic crystal operating in the …

Chirality extends the class of negatively refracting metamaterials by endowing a richer
palette of electromagnetic properties. Chiral metamaterials can support negative refraction …

The role of a chiral quantum-dot molecule (QDM) system in controlling and enhancing the
Goos-Hänchen (GH) shift is revealed here. The proposed setup is a four-level atomic system …

It is theoretically shown that the negative Goos–Hänchen shifts near resonance, Re [k_zd]=
m?, can be an order of magnitude larger than the wavelength for both TE-and TM-polarized …

We show that a modulated Gaussian beam undergoes negative refraction at the interface
between a positive and negative refractive index material. While the refraction of the beam is …

Most animals can skilfully conceal themselves when stationary, but they may become
apparent as soon as they move. Here we use stereo cameras to reconstruct the movements …
