A metamaterial (from the Greek word μετά meta, meaning “beyond” and the Latin word materia, meaning “matter” or “material”) is any material engineered to have a property that is not found in naturally occurring materials. Metamaterials offer the potential to create superlenses.
What is a Pentamode?
A pentamode metamaterial is an artificial three-dimensional structure which, despite being a solid, ideally behaves like a fluid. Thus, it has a finite bulk but vanishing shear modulus, or in other words it is hard to compress yet easy to deform.
What does meta materials make?
META designs and manufactures functional films that are engineered at nanoscopic levels to control light and other electromagnetic waves. META’s products are called metamaterials because they have advanced properties not inherent in the material’s original form.
Are metamaterials real?
Metamaterials are artificial materials that can achieve electromagnetic properties that do not occur naturally, such as negative index of refraction or electromagnetic cloaking. These unit cells are microscopically built from conventional materials such as metals and dielectrics like plastics.
What is chiral metamaterial?
Chiral metamaterials generally consist of arrays of planar metallic or dielectric gammadions on a substrate, where, if linearly polarized electromagnetic wave such as GHz, THz, or visible light is incident on the array, it becomes elliptically polarized upon interaction with the gammadions with the same handedness as …
Is negative refraction possible?
Negative refraction occurs at interfaces between materials at which one has an ordinary positive phase velocity (i.e., a positive refractive index), and the other has the more exotic negative phase velocity (a negative refractive index).
What kind of company is meta materials?
photonics company
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.
