Photonic metamaterials are man-made structures composed of tailored micro-or
nanostructured metallodielectric subwavelength building blocks. This deceptively simple yet …

Solar energy is abundant and environmentally friendly. Light trap** in solar-energy-
harvesting devices or structures is of critical importance. This article reviews light trap** …

The advent of negative index materials has spawned extensive research into metamaterials
over the past decade. Metamaterials are attractive not only for their exotic electromagnetic …

We demonstrate, for the first time, a spatially dependent metamaterial perfect absorber
operating in the infrared regime. We achieve an experimental absorption of 97% at a …

Electromagnetic metamaterials (MMs) and metasurfaces (MSs) are artificial media and
surfaces with subwavelength separations of meta-atoms designed for anomalous …

The imaging resolution of conventional lenses is limited by diffraction. Artificially engineered
metamaterials now offer the possibility of building a superlens that overcomes this limit. We …

PERSPECTIVES wavelength replace the atoms and molecules of a conventional material,
scientists can circumvent this limitation. Metamaterials can be designed to exhibit both …

Over the past several years, metamaterials have been introduced and rapidly been adopted
as a means of achieving unique electromagnetic material response. In metamaterials …

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 analyze the properties of microstructured materials with negative refraction, the so-called
left-handed metamaterials. We consider a two-dimensional periodic structure created by …
