Metamaterial

Ролик рвёт крышу!!! Перед просмотром убедитесь в состоянии своей нервной системы!!!

Метаматериа́л — материал, природные свойства которого обусловлены не столько природными физическими свойствами, сколько периодической микроструктурой создаваемой человеком.

Metamaterials are artificial materials engineered to have properties that may not be found in nature.

As shown in this video, a door latch and a pair of pliers are among the mechanisms created without screws, bolts or other fixings by researchers working with metamaterials.

The team at the Hasso Plattner Institute's Human Computer Interaction Lab design objects that move despite being 3D printed as one single part.

Specifically, the objects have controlled directional movement, which means they can perform set mechanical functions, like gripping something or latching a door.

// Abstract
Recently, researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically

Demonstration of the fractal advantage by adding a slip-on fractal metamaterial sleeve to a basic monopole antenna, showing dramatic improvements in SWR, gain, and bandwidth. Lab prototype shown for heuristic purposes; this technology is used in a variety of the firm's products, and the firm is the IP holder on the technology. The technology is offered exclusively through the firm. Kindly submit your questions

Hyperbolic metamaterials are an exciting recent development in the field of nanophotonics. They combine the properties of metals and dielectrics -- an idea so crazy that it just might work!

This lecture introduces the student to metamaterials. It categorizes metamaterials into resonant and nonresonant types. It is not a comprehensive...

Phil Saunders of SpaceChannel.org and Nikolay Zheludev of the University of Southampton, U.K., have graciously permitted OPN to reproduce this fascinating video, which is related to Zheludevs October OPN feature on metamaterial-induced transparency. It explores the science behind metamaterials—crystalline-like sub-wavelength arrangements of electromagnetic resonators that can exhibit exotic optical properties such as negative refraction and cloaking. With a focus on work being conducted at the University o

Homogenization of Maxwell equations for metamaterials, Arkadi Chipouline

A lecture given by the 2013 winner of the Isaac Newton medal, Professor Sir John Pendry, Imperial College London, and chaired by Professor Roy Sambles, Exeter University.

The slab is gradually squeezed in the vertical direction by a maximum of about 12% of its total height, while the horizontal squeezing (confinement) is fixed at 15% of the (unconfined) width. At about half of the maximum squeezing (0:03 in the video), the stiffness suddenly drops, when the orientation of the squished holes switches. The equivalent event during the reverse process occurs at slightly less squeezing (0:11), demonstrating that this degree of horizontal confinement leads to hysteresis.

Topological mechanical metamaterials are artificial materials that harbour robust motion at edges. The lattice of gears shown in this video exhibits such a motion, which is confined to one edge of the system while the rest of the lattice, including the other edge, remains rigid. The difference in flexibility of the left and right edges originates from a topological index (the "polarization") that characterizes the lattice mode spectrum. Akin to the number of holes in a donut or pretzel, this index captures

In principle a "perfect lens" could be created that opens up a brave new world of scientific investigation, particularly in nanotechnology and the biosciences.

The key requirement of these instruments is to devise a cunning way of getting around the diffraction limit, which restricts the resolution of images produced with optical light.

This film takes you to Imperial College London to investigate one promising route to a perfect lens that uses artificial structures known as metamaterials.

Метаматериалы (от греч. «мета» - «за пределами», «сверх») - это искусственные материалы, обладающие электромагнитными свойствами не встречающимися в природе. М. состоят не из атомов и молекул, как обычные вещества, а из микроструктур: крошечных, меньше микрона, искусственных металлических резонаторов.
