Researchers devise a way to capture and release electromagnetic waves inside a metamaterial

(Phys.org) —A team of researchers at Kyoto University in Japan has discovered a way to capture and hold electromagnetic waves inside of a metalmaterial and then release them. As the group describes in their paper they've uploaded to the preprint server arXiv, the process involved creating a metamaterial with two different types of capacitors—one that absorbs or radiates waves and another that traps them.

X-48 Project Completes Flight Research for Cleaner, Quieter Aircraft

NASA's remotely piloted X-48C hybrid-wing-body subscale aircraft, which demonstrates technology concepts for cleaner and quieter commercial air travel, completed an eight-month flight research campaign on April 9.

Bose-Einstein condensates evaluated for quantum computers

Physicists have examined how Bose-Einstein condensates (BEC) might be used to provide communication among the nodes of a distributed quantum computer. The researchers determined the amount of time needed for quantum information to propagate across their BEC.

Physicists and astronaut discuss cosmic ray detector's findings of possible signs of dark matter

Two MIT physicists and an alumnus who's a NASA astronaut spoke on campus earlier this week, describing an experiment that's been 18 years in the making and yielded its first significant results just last week.

Diamond as a building material for optical circuits

The application of light for information processing opens up a multitude of possibilities. However, to be able to adequately use photons in circuits and sensors, materials need to have particular optical and mechanical properties. Researchers have now for the first time used polycrystalline diamond to manufacture optical circuits.

NASA Imaging Sensor Prepares for Western Wildfire Season

Airborne imaging technology developed at NASA and transferred to the U.S. Department of Agriculture's Forest Service (USFS) in 2012 is being tested to prepare for this year's wildfire season in the western United States.
