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 ...

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 ...

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.

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 ...

A bad wireless reception, the noise in the radio signal or poor visibility in the fog – all these annoyances have to do with the fact that waves such as visible light or microwave signals are ...

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 ...

A tailor-made structure may make microwave WiFi signals more transmittable through walls without reflection, according to new research. This works in much the same way as anti-reflective coating on a ...

A ripple tank can be used to investigate the frequency close frequencyThe number of waves produced each second. The unit of frequency is hertz (Hz)., wavelength close wavelengthThe length of a single ...
