What is metamaterial used for?
Metamaterials are composite media that can be engineered to exhibit unique electromagnetic properties. Made up from subwavelength building blocks (most often based on metals), these metamaterials allow for extreme control over optical fields, enabling effects such as negative refraction to be realized.
What are examples of metamaterials?
Some examples of available metamaterials are negative index metamaterials, chiral metamaterials, plasmonic metamaterials, photonic metamaterials, etc.
What kind of company is metamaterials?
Metamaterial Exchangeco Inc, formerly Metamaterial Inc is a smart materials and photonics company. Its product includes nanoweb, metaAIR, and Glucowise. the company is specialized in nanofabrication, design, and manufacturing of highly functional products that harness the power of light.
What is metamaterial based antenna?
Metamaterial antennas are a class of antennas which use metamaterials to increase performance of miniaturized (electrically small) antenna systems. However, this class of antenna incorporates metamaterials, which are materials engineered with novel, often microscopic, structures to produce unusual physical properties.
How does a Metasurface work?
The principle of operation of metasurfaces is based on the phenomenon of diffraction. Any flat periodic array can be viewed as a diffraction lattice, which splits the incident light into a few rays. In contrast, active metasurfaces allow the dynamic control of its optical properties under external stimuli.
Is Metamaterials a real company?
Metamaterial Technologies, Inc. (MTI) manufactures and distributes optical solutions and nano-composites. The Company designs, develops and manufactures innovative optical thin film products, using patent pending metamaterial designs, chemical deposition, and optical characterization.
Are metamaterials profitable?
Quality Earnings: MMAT is currently unprofitable. Growing Profit Margin: MMAT is currently unprofitable.
How does a metamaterial antenna work?
The metamaterials can be applied to improve bandwidth, power gain, or to create compact, multifrequency-band antennas. To apply metamaterials in an antenna, the first is to design their unit cells, which are considered as atoms, creating special properties of the metamaterial at the desired frequency.
What is conventional antenna?
The conventional antenna has designed for same dimensions as metamaterial loaded U-shaped patch antenna. Both antennas are fed by using co-planar waveguide (CPW) method. Simulation results for return loss and radiation pattern of both proposed and conventional antenna are shown and compared with practical results.
What are metamaterials and why do we need them?
Metamaterials are composite media that can be engineered to exhibit unique electromagnetic properties. Made up from subwavelength building blocks (most often based on metals), these metamaterials allow for extreme control over optical fields, enabling effects such as negative refraction to be realized.
What are the different applications of metamaterials?
Antennas. Metamaterial antennas are a class of antennas that use metamaterials to improve performance.
What are metamaterials made from?
A metamaterial (from the Greek word μετά meta, meaning “beyond”) is a material engineered to have a property that is not found in naturally occurring materials. They are made from assemblies of multiple elements fashioned from composite materials such as metals or plastics.
What are electromagnetic metamaterials?
Electromagnetic metamaterials Hyperbolic. Hyperbolic metamaterials (HMMs) behave as a metal for certain polarization or direction of light propagation and behave as a dielectric for the other due to the negative and positive Bandgap. Electromagnetic bandgap metamaterials (EBG or EBM) control light propagation. Chiral.
