For more than half a century, the idea that light or radio waves could suddenly reverse in time sounded like a thought experiment, not a laboratory result. Now, a series of meticulous experiments has ...

Time reflections, or spatial reflections, occur when "electromagnetic radiation in the form of light or sound waves hit a mirror or wall, respectively," resulting in a reflection, like a mirror image ...

Scientists have hypothesized for over six decades the possibility of observing a form of wave reflections known as temporal, or time, reflections. Researchers detail a breakthrough experiment in which ...

Physicists have experimentally reversed electromagnetic waves in time, confirming a theoretical prediction that has stood for ...

A wave propagating through an inhomogeneous medium is usually partially reflected, which is often undesirable from a practical point of view. Although the reflection from a sharp interface can be ...

Researchers have developed new metasurfaces for the arbitrary manipulation of reflected waves, essentially breaking classical reflection law to engineer it at will. In our daily lives, we can find ...

THE principle that a regularly stratified medium selectively reflects a monochromatic beam of radiation incident on it at the appropriate angle is well known and forms the basis for the X-ray analysis ...

NEW YORK, March 13, 2023 — When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored ...
