We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

Metamaterials (MM) are artificially designed materials that possess unique properties due to
their geometrical design. They also display some peculiar properties, such as negative …

Metamaterials are artificial structures with the ability of exhibiting unusual and exotic
electromagnetic properties such as the realisation of negative permittivity and permeability …

Recent demonstrations of negative refraction utilize three-dimensional collections of discrete
periodic scatterers to synthesize artificial dielectrics with simultaneously negative permittivity …

Since the advent of quantum mechanics and the clear demonstration of the existence
of'matter waves', physicists have never failed to take advantage of concepts and theoretical …

A novel composite right-/left-handed (CRLH) backward-wave coupled-line directional
coupler with arbitrary coupling level and broad bandwidth is presented, explained by …

We report experimental observation of an inverse Doppler shift, in which the frequency of a
wave is increased on reflection from a receding boundary. This counterintuitive effect has …

A transmission line (TL) approach of left-handed (LH) materials is proposed. The
transmission characteristics of an ideal LH-TL are presented, the constitutive parameters of …

A composite medium consisting of an array of fine wires and split-ring resonators has been
previously used to experimentally verify a negative index of refraction. We present a …

The effect of surrounding an electrically small dipole antenna with a shell of double negative
(DNG) material (/spl epsiv//sub r/< 0 and/spl mu//sub r/< 0) has been investigated both …
