A negative-index metamaterial causes light to refract, or bend, differently than in more common positive-index materials such as glass lenses. Negative-index metamaterial or negative-index material (NIM) is a metamaterial whose refractive index for an electromagnetic wave has a negative value over some frequency range. [1]
Importantly, this modulation does not impact the magnetic response characteristics of the metamaterial. These elements could be combined with the previously developed nonlinear magnetic metamaterials in order to create negative index media with a control over both electric and magnetic nonlinearities. [22]
The earliest research in metamaterial antennas was an analytical study of a miniature dipole antenna surrounded with a metamaterial. This material is known variously as a negative index metamaterial (NIM) or double negative metamaterial (DNG) among other names. [10]
Negative-index metamaterial array configuration, which was constructed of copper split-ring resonators and wires mounted on interlocking sheets of fiberglass circuit board. The total array consists of 3×20×20 unit cells with overall dimensions of 10 mm × 100 mm × 100 mm (0.39 in × 3.94 in × 3.94 in).
A periodic array of SRRs was used for the first demonstration of a negative index of refraction. [17] For this demonstration, square shaped SRRs, with the lined wire configurations, were fabricated into a periodic, arrayed, cell structure. [17] This is the substance of the metamaterial. [17] Then a metamaterial prism was cut from this material ...

A comparison of refraction in a left-handed metamaterial to that in a normal material Video representing negative refraction of light at uniform planar interface.. One can choose to avoid directly considering the Poynting vector and wave vector of a propagating light field, and instead directly consider the response of the materials.
S&P currently has a 'BBB+' - investment grade - rating on the firm, whose stock has lost about a fifth of its value this year in the face of weak revenue growth and a $15.63 billion debt load as ...
