Much of the confusion in the preceding Comment is resolved once the correct origin and definition of the phrase Negative Phase Velocity (NPV) propagation is recognised. Markel's claim that Im (k2t) < o is a predictor for negative refraction is incompatible with taking μ0-1 E × B as the...
1、What is metamaterial?The first research on metamaterials was on negative refractive index metamaterials. In 1968, the Soviet scientist Veselago first proposed the concept of materials with negative dielectric constant and negative magnetic permeability at the same time, and predicted that these ...

Superlenses formed from metasurfaces displaying negative permittivity and permeability (negative refractive index) that can focus light beyond the diffraction limit, especially useful in microscopy Phase compensation media, which combine double-negative media with positive-indexed materials Cloaked surfaces form...
subwavelength dimensions. The technology is an emerging area, but issues of energy loss in certain spectral regions remain. Potential applications for plasmonics include chemical and biological sensing, subwavelength imaging and superlenses, negative refractive index materials and invisibility, and solar ...

What is a plano concave? A plano concave lens isan optical lens with one concave surface and one flat surface. It has a negative focal length, and can be used for light projection, beam expansion, or to increase focal length of an optical system. ...
