What is the metamatory?

Metamamarial is a material with special properties derived from its structure rather than from the chemical composition. The most famous metamaterial is materials with a negative refractive index, which means that light bending in the "wrong way" - that is, significantly more than any material with a positive refractive index.

All materials found in nature have a positive refractive index. Negative quarry index materials have applications in "SuperLENSES" - special lenses with the potential to solve the properties less than the wavelength of visible light and the possible capture of invisibility that smoothly direct visible light around the object than absorb or reflect it. These materials can also be used in Plasmonics, in an exotic new area of ​​computer technology, which uses wool density in carriers for calculations.S, lenses, etc. Repeat cellular components, with cell size roughly the same as the size of the wool length of the electromagnetic radiation. Metamaterial designed pRO Red -mound microwaves should therefore have cells in the range of millimeters, while the metamaterial designed for optic applications would have much smaller cells, around the range of 380 nm - 780 nm.

Metamaterials are often associated with nanotechnology, as nanometers are measured by small recurring cellular structures used for optical applications. Metamaterial creation may require new ways of production that are only possible by nanotechnology. As nanotechnology has progressed in the coming decades, it unlocks new metamators and reduces their costs.

There is at least one known natural metamaterial (but no natural metamators with a negative refractive index): Opal. Opal IS composed of cristobality, high -temperature quartz polymorph and tridymity produced in volcanic eruptions. The resulting material is made up of a huge number of small mineral cells that will constantly fall in relation to another,And it creates a macro-meter of the effect of a beautiful display of more colors, the most prominently brilliant blue.
