(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 ...
(Phys.org) —Researchers have discovered an alternative way to make an invisibility cloak that departs from other attempts to do so. Attempts in the past have been via metamaterials, created by assembling structures that ...
A time crystal, as originally proposed in 2012, is a new state of matter in which the particles are in continuous oscillatory motion. Time crystals break time-translation symmetry. Discrete time crystals do so by oscillating ...
(PhysOrg.com) -- Duke University engineers have created a new generation of lens that could greatly improve the capabilities of telecommunications or radar systems to provide a wide field of view and greater detail.
