Scientists Develop Tiny Multi-Layer Lenses for High-Performance Portable Optics
Learn about the innovative multi-layer metalens design and its potential applications in portable devices. It is the first-ever discovery which would allow people to see the world differently. Unlike traditional lenses, these are fabricated by stacking together multiple thin layers of so-called metamaterials rather than using a single one.

Metamaterial Breaks Thermal Symmetry, Enables One-Way Heat Emission
Scientists have created a groundbreaking metamaterial that breaks Kirchhoff’s law by emitting 43% more mid-infrared radiation in one direction than it absorbs. Built from layered InGaAs and tested at 512°F with a 5T magnetic field, the structure exhibits record thermal nonreciprocity. This breakthrough enables controlled one-way heat flow, a ste...

Scientists Move Objects Without Using Their Hands, Here's How
The technique could possibly open the door for using contactless manipulation in industries such as robotics and manufacturing.

'Hyperlens' Can Show Tiny Objects That Elude the Most Powerful Optical Systems
There is a great need in healthcare, nanotechnology and other areas to improve our ability to see tiny objects that elude even the most powerful optical systems.

New Metamaterial May Pave Way for Photonics to Replace Electronics
"Our material can put a twist into light - that is, rotate its polarisation - orders of magnitude more strongly than natural materials."
-
Metamaterials can be used to perform mathematical operations like calculus
Metamaterials change the shape of an incoming light wave in a way akin to mathematical operations.
-
In the hunt for invisibility, other benefits seen
A new way of assembling things, called metamaterials, may in the not too distant future help to protect a building from earthquakes by bending seismic waves around it.
-
'Metamaterials' show promise for data transmission, wireless charging and more
Metamaterials are materials that exhibit properties not found in nature. They are made by assembling materials at the nanoscale.
