Researchers in Drexel University’s College of Engineering have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The ...

Ship waves, the complex patterns generated as vessels displace water, remain a subject of significant scientific and engineering interest. Traditionally described by Kelvin’s theory of ship wakes, ...

Fig. 1 THz wave generation from MoS2 through quantum interference. (a) Schematic diagram of THz wave generation from MoS2 under two-color light excitation at normal incidence. (b) THz waveforms ...

For more than a century, scientists have known that waves can behave in ways that seem to defy common sense, from freak walls of water in the open ocean to ghostly ripples inside atoms. What has ...

Tim Kovachy is in the Department of Physics and Astronomy and at the Center for Fundamental Physics, Northwestern University, Evanston, Illinois 60208, USA. Quantum mechanics predicts that single ...

Physicists at MIT recreated the double-slit experiment using individual photons and atoms held in laser light, uncovering the true limits of light’s wave–particle duality. Their results proved ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250149, discusses a quarter-wave geometric-phase route to practical 3D ...
