The abundant untapped momentum of solar photons is becoming increasingly attractive as a means to propel spacecraft with an attached solar sail. Decades of theoretical mission studies have examined ...
US researchers have made metafilms of both copper squares etched on a wafer and yttrium iron spheres embedded in a matrix. The US National Institute of Standards and Technology (NIST) has metamaterial ...
With the rapid development of nanophotonics, spectrally selective infrared stealth technology has achieved great success through the design of metamaterials. However, as the background environment is ...
Recent research at the National Institute of Standards and Technology has demonstrated that thin films made of “metamaterials”—manmade composites engineered to offer strange combinations of ...
A recent study published in the journal Cell Reports Physical Science presented a biodegradable metafilm made from poly(lactic acid) (PLA) for durable and efficient ...
A Rochester Institute of Technology researcher could more than double the performance of solar sails by creating diffractive metafilm sails. This will initially be used to raise cubesats to higher ...
A new biodegradable film developed by scientists in China and Australia could slash building energy use by up to 20 per cent and keep surfaces up to 9.2C cooler without using any electricity, ...
