New metamaterials are easily manufacturedAshley N. Rice, ashley.rice@photonics.com By combining theory and practice, two groups of Penn State scientists have designed low-loss optical metamaterials that are easily manufactured for custom applications with dispersions that can be tuned over large ...
Metamaterials, invented at Duke University 20 years ago, are arrays of tiny devices that can interact with incident electromagnetic radiation. Metamaterials have been used to create negative refractive index materials (holding the potential for more compact lenses) and even an invisibility cloak (where ...
“While snapology provides the geometric starting point for our research, our focus here is on the foldability of these structures and how this can lead to new designs for transformable metamaterials," Overvelde writes in a new paper, published inNature Communications. ...
“Metal-based metamaterials are much easier to tune to these frequencies, but when metal heats up to the temperatures required in these types of devices, they tend to melt,” said Padilla. “You need a dielectric metamaterial that can withstand the heat. And now that we have the machine lea...
Following complex electromagnetic simulation analyses, the team developed metamaterials based on a material that integrated plastic and carbon particles.Reducing ReflectionWhile the plastic composite displayed high absorption in the required microwave area of the electromagnetic spectrum, the surface of this ...
“A microscopic, ultrathin, ultralightweight, flat optical device based on a metasurface is an impressive technique with great potential, as it can not only perform the functions of the conventional optical devices, but also demonstrate multiple functions depending on how its metasurface is designed...
Moreover, in mechanical metamaterials there are no spurious frequency components due to the non-linearity of active devices, and they lend themselves to high-power applications because there is no risk of an electrical breakdown. On the other side, the use of tunable materials such as ferroele...
"Metamaterials will potentially allow us to do many new things with light, things we don't even know about yet. I can't even imagine what all the applications might be," Garcia said. "This is a new tool kit to do things that have never been done before." ...
