Reconfigurable materials can do amazing things. Flat sheets transform into a face. An extruded cube transforms into dozens of different shapes. But there’s one thing…
Enormous potential range of applications. MIT engineers and colleagues report important new advances on a tunable metasurface, or flat optical device patterned with nanoscale structures,…
A new approach to producing metamaterials draws on kirigami techniques to make three-dimensional, reconfigurable building blocks that can be used to create complex, dynamic structures….
Over the past 20 years, scientists have been developing metamaterials, or materials that don’t occur naturally and whose mechanical properties result from their designed structure…
Sometimes, the inside of a material can determine what happens on the outside. A team of physicists from the University of Amsterdam has devised a…
A new approach to trapping light in artificial photonic materials by a City College of New York-led team could lead to a tremendous boost in…
Lawrence Livermore National Laboratory (LLNL) researchers have designed a new class of 3D-printed lattice structures that combine lightweight and high stiffness, despite breaking a rule…
New research has demonstrated how the nano-architecture of a silkworm’s fiber causes “Anderson localization of light,” a discovery that could lead to various innovations and…
An international team consisting of Russian and German scientists has made a breakthrough in the creation of seemingly impossible materials. They have managed to create…
A team of scientists have invented an ultra-thin invisibility cloak that can conform to the shape of an object and conceal it from detection with…
Physicists have created the first experimental wormhole that can connect two regions of space magnetically. It consists of a tunnel that transfers the magnetic field…
A team of physicists has managed to make homogenous cylindrical objects completely invisible in the microwave range without relying on metamaterial coatings. The method is…
A newly published study details how “digital metamaterials” could help bring invisibly cloaks closer to reality. The concept of “digital metamaterials” – a simple way…
Researchers from UCLA have developed a terahertz modulator that performs across a wide range of the terahertz band with very high efficiency and signal clarity,…
Using metamaterials, researchers at the Karlsruhe Institute of Technology developed a mechanical invisibility cloak that hides objects from touch. In the past years, invisibility cloaks…
By combining supramolecules based on block copolymers with gold nanoparticles, Berkeley Lab researchers have created self-assembling nanoparticle arrays that can form a highly ordered thin…
Researchers from Purdue University have created superlattices from layers of metal titanium nitride and aluminum scandium nitride, bringing “hyperbolic metamaterials” closer to reality. West Lafayette,…
By surrounding an object with small antennas that collectively radiate an electromagnetic field, engineers demonstrate active electromagnetic cloaking. Invisibility cloaking is no longer the stuff…
