The study of acoustic wave scattering and diffraction in waveguide structures lies at the forefront of both theoretical and applied acoustics. It encompasses the intricate processes by which sound ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Using a highly coherent positronium beam, the researchers observed clear diffraction patterns after transmission through a graphene film, confirming its wave-like behavior. One of the discoveries that ...

Surface plasmons are collective oscillations of free electrons that occur at the interface between a metal and a dielectric medium, such as air or glass. These oscillations are coupled with ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Light microscopy is the only way in which we can look inside a living cell, or living tissues, in three dimensions. An electron microscope only gives a two-dimensional view, and the organic sample ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...
