PROGRESS IN CLOAKING. "The first invisibility cloaks worked only at microwave frequencies but in only a few years, physicists have found ways to create cloaks that work for visible light, for sound and for ocean waves. They’ve even designed illusion cloaks that can make one object look like another." https://lnkd.in/eVgKzAT View in LinkedIn

DEFENSE AND METAMATERIALS. "In the last 5 years there has been great involvement of industry and particularly of the defence establishment in the USA who run several multi mullion dollar programs on metamaterials based at DARPA, WPAFB and Sandia." https://lnkd.in/eM8vuRF View in LinkedIn

EM DISTORTION, THE START. "Invisibility cloaks are the result of physicists’ newfound ability to distort electromagnetic fields in extreme ways. The idea is steer light around a volume of space so that anything inside this region is essentially invisible." https://lnkd.in/eVgKzAT View in LinkedIn

INTEREST IN METAMATERIALS. "The impact of metamaterials is widespread with almost every major organisation concerned with electromagnetism showing interest in this field." https://lnkd.in/eM8vuRF View in LinkedIn

"IT'S NO ILLUSION: Science has found a way to make not just objects but entire events disappear..."The concepts are basically quite simple," said Paul Kinsler, a physicist at Imperial College London, who created the idea with colleagues Martin McCall and Alberto Favaro...this cloak would use special materials filled with metallic arrays designed to adjust the speed of light passing through." https://lnkd.in/eka5NuE View in LinkedIn

DARPA FUNDED TIME-LENS. "The researchers created what they call a time lens, which can manipulate and focus signals in time, analogous to the way a glass lens focuses light in space." Inspired by a theoretical proposal by Martin McCall at Imperial College in 2010, “But his method required an optical response from a material that does not exist," which they overcame. https://lnkd.in/e4aJQTV View in LinkedIn

HOLE IN SPACE. "To achieve spatial cloaking, the index of refraction is manipulated to flow light from a probe around an object in such a way that a ‘hole’ in space is created, and the object remains hidden." https://lnkd.in/egaTnRz View in LinkedIn

COMMUNICATION BETWEEN PAST AND FUTURE. "We apply the methods of transformation optics to theoretical descriptions of spacetimes that support closed null geodesic curves....Through transformation optics, this metric is analogous to a material that in theory should allow for communication between past and future." https://lnkd.in/evYqK4d View in LinkedIn

DEMONSTRATION OF TEMPORAL CLOAKING using changes in refractive index. "Recent research has uncovered a remarkable ability to manipulate and control electromagnetic fields to produce effects such as perfect imaging and spatial cloaking." https://lnkd.in/egaTnRz View in LinkedIn

SIGNAL CODING. "Application of the temporal cloak system in optical signal encoding and decoding has been proposed. It has been demonstrated that the developed scheme can be applied in optical signal processing and fiber-optical secure communications." https://lnkd.in/eztPSPd View in LinkedIn
