Researchers have developed a surprising method to eliminate wave reflections. The method allows the calculation of a tailor-made anti-reflective structure. It can be used, for example, to design an ...

Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

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 ...

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 ...

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 ...

Journal of Coastal Research, Vol. 3, No. 2 (Spring, 1987), pp. 153-167 (15 pages) A new mode of beach response to changes in wave height is identified for reflective beaches where waves break close to ...

Sketch of the concept: a disordered medium (top) is made perfectly transmitting by placing a custom-made anti-reflection coating in front of it (bottom). (Courtesy: TU Wien) A new technique that ...

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 ...

Compared to general metal reflectors, the new product is capable of reflecting millimetre waves in a more targeted manner. As a result, there are fewer restrictions on installation, making it possible ...
