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

TIME CLOAK TO CONCEAL MESSAGES. "A “time cloak” that conceals events rather than objects can hide secret messages through a trick of light, making information invisible to all but the intended recipient. Like an invisibility cloak that makes something disappear in plain sight, a time cloak makes an event disappear in time. It works by manipulating light traveling along an optical fibre." https://lnkd.in/eAbVHjQ View in LinkedIn

A TIME LENS. "Such a time-lens can be made using an electro-optic modulator, for example, and has a variety of familiar properties. This time-lens can, for example, magnify or compress in time." https://lnkd.in/eVgKzAT View in LinkedIn

INTERESTING SEQUELAE. "Just as its easy to make a lens that focuses light in space using diffraction, so it is possible to use dispersion to make a lens that focuses in time." https://lnkd.in/eVgKzAT View in LinkedIn
