摘要：

Light can be made to bend, or refract, backwards, by the use of the right type of man-made materials. Scientists, following this concept, are looking to translate negative refraction into positive applications such as subwavelength, high-resolution imaging across the electromagnetic spectrum. Negative index materials (NIMs) can match the impedance, or the properties of free space (air without matter), and can result in zero reflectance for all the incident angles. The NIM community has succeeded in fabricating and demonstrating the magnetic response of split ring resonator (SRR) structures operating at 2 THz, 6THz, and 100 and 200 THz. Scientists are looking to develop the technology and methods that can translate these novel materials into useful applications.
