Recently, artificially constructed metamaterials have become of considerable interest,
because these materials can exhibit electromagnetic characteristics unlike those of any …

The concept of metamaterials originates from the proposal of left-hand materials with
negative refractive index, followed by which, varieties of metamaterials with kinds of fantastic …

Using the freedom of design that metamaterials provide, we show how electromagnetic
fields can be redirected at will and propose a design strategy. The conserved fields—electric …

Recent theory has predicted a superlens that is capable of producing sub–diffraction-limited
images. This superlens would allow the recovery of evanescent waves in an image via the …

Optical metamaterials have presented an innovative method of manipulating light.
Hyperbolic metamaterials have an extremely high anisotropy with a hyperbolic dispersion …

Artificially engineered metamaterials are now demonstrating unprecedented
electromagnetic properties that cannot be obtained with naturally occurring materials. In …

In this paper, a new approach for the development of planar metamaterial structures is
developed. For this purpose, split-ring resonators (SRRs) and complementary split-ring …

Negative refraction is currently achieved by driving the magnetic permeability and electrical
permittivity simultaneously negative, thus requiring two separate resonances in the …

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 …

Metamaterials are artificial structures that can be designed to exhibit specific
electromagnetic properties not commonly found in nature. Recently, metamaterials with …
