Metamaterial Radar Is Exactly What Delivery Drones Need
10 Nov | IEEE SpectrumFull Text External Link Indicator
"As we’ve pointed out over the last few years, there are some issues with the idea of urban or suburban delivery drones. Besides the fact that they’re illegal right now, the biggest technological problem is that none of the delivery drones that we’ve seen so far seem to have any kind of sense-and-avoid capability that could realistically deal with the challenges of urban airspace, including everything from other drones to light aircraft to birds to trees to overhead wiring." by Evan Ackerman
Silicon-based metamaterials could bring photonic circuits
03 Nov | Phys.OrgFull Text External Link Indicator
"New transparent metamaterials under development could make possible computer chips and interconnecting circuits that use light instead of electrons to process and transmit data, representing a potential leap in performance." by Emil Venere. Read more at:
Large-scale metamaterials could combat earthquake shocks
03 Nov | Physics WorldFull Text External Link Indicator
"Future cities could be protected from destructive earthquakes using large-scale metamaterial shields to dampen seismic waves, according to new work done by researchers in Europe. The team used 3D modelling to demonstrate the potential of the shields, which are made of arrays of cavities dug into the ground." by Ian Randall
Thermal metamaterial innovation
03 Nov | Energy Harvesting JournalFull Text External Link Indicator
"An international research team has used a "thermal metamaterial" to control the emission of radiation at high temperatures, an advance that could bring devices able to efficiently harvest waste heat from power plants and factories." Read more at:
Adding a topological fold to origami metamaterials
03 Nov | Physics WorldFull Text External Link Indicator
"A metamaterial that is soft along one edge and rigid along the other, yet also displays mechanical topological properties, has been developed by an international team of researchers. This is the first time that topological origami and kirigami techniques have been applied experimentally to metamaterials – artificial materials with tunable, well-defined properties. Apart from having developed a metamaterial with two distinct topological phases, the team is also working on theoretical guidelines for the future design and development of such materials." by Tushna Commissariat
Distance wireless charging enhanced by magnetic metamaterials
03 Nov | Universitat Autònoma de Barcelona. "Distance wireless charging enhanced by magnetic metamaterials." ScienceDaily. ScienceDaily, 10 May 2016.Full Text External Link Indicator
"Researchers have developed a system which efficiently transfers electrical energy between two separate circuits. The system, made with a shell of metamaterials which concentrates the magnetic field, could transmit energy efficiently enough to charge mobile devices without having to place them close to the charging base."
The laws of physics make a human invisibility cloak pretty much impossible

Sound-proof metamaterial inspired by spider webs
03 Nov | Phys.OrgFull Text External Link Indicator
"Spider silk is well-known for its unusual combination of being both lightweight and extremely strong—in some cases, stronger than steel. Due to these properties, researchers have been developing spider-silk-inspired materials for potential applications such as durable yet lightweight clothing, bullet-proof vests, and parachutes." by Lisa Zyga.

Quantum Computing: How Close Are We?
03 Oct | Optics and Photonics NewsFull Text External Link Indicator
"Industry has joined the race to build a universal quantum computer. But the task is daunting." by Edwin Cartlidge
Nanoscale Wireless Communication Operates at Visible Wavelengths for the First Time
13 Sep | IEEE SpectrumFull Text External Link Indicator
"Currently, wireless optical communication on computer chips occurs at near-infrared wavelengths. But if visible light could be used in these on-chip optical communications, the chips could be miniaturized significantly because the wavelengths in that portion of the spectrum are much smaller."
