WebNov 9, 2015 · The proposed chiral metamaterials were shown to have optical activities at least two orders of magnitude greater than natural materials and some even show a negative refractive index . On the other hand, one of the advantages of metamaterials is the tunability of their optical properties through geometric and material parameters.
WebNegative refraction is the electromagnetic phenomenon where light rays become refracted at an interface that is opposite to their more commonly observed positive refractive properties. Negative refraction can be obtained by using a metamaterial which has been designed to achieve a negative value for (electric) permittivity (ε) and (magnetic) … WebMay 13, 2016 · Thus, the chiral index of these greatly enriched SWNTs could be unambiguously assigned as (15,2). This is also in agreement with the theoretical analysis of the SWNT growth kinetics—the growth rates of zigzag tubes should be slower than those of other tubes by several orders of magnitude and thus must be rare (13, 32).

WebIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/ k aɪ ˈ r æ l ɪ t i /). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an …
