In the late nineteenth century, Heinrich Hertz demonstrated that the electromagnetic
properties of materials are intimately related to their structure at the subwavelength scale by …

Usually, investigators in materials science have asked:“What properties does a certain new
material or structure have?” Now, the inverse problem arises:“I want to achieve certain …

Metamaterials, as artificially structured materials composed of subwavelength arrays of
resonant unit cells, can exhibit exotic properties beyond those accessible to natural …

We present waveguides with photonic crystal cores, supporting energy propagation in
subwavelength regions with a mode structure identical to that in telecom fibers and develop …

Metamaterials exhibit numerous novel effects,,,, and operate over a large portion of the
electromagnetic spectrum,,,,. Metamaterial devices based on these effects include gradient …

Metamaterials are artificially structured media with unit cells much smaller than the
wavelength of light. They have proved to possess novel electromagnetic properties, such as …

Metamaterials provide an unprecedented ability to manipulate electromagnetic waves and
are an enabling technology for new devices ranging from flat lenses that focus light beyond …

The ability to control wave propagation is of fundamental interest in many areas of physics.
Photonic crystals proved very useful for this purpose but, because they are based on Bragg …

Metamaterials can possess extraordinary properties not readily available in nature. While
most of the early metamaterials had narrow frequency bandwidth of operation, many recent …

Metamaterials have the potential to create optical devices with new and diverse
functionalities based on novel wave phenomena. Most practical optical systems require that …
