Whistler mode chorus waves are electromagnetic emissions common in planetary magnetospheres. Among other impacts, their scattering of magnetospheric electrons is one driver for the formation of ...

A collaborative research team led by Interim Head of Physics Professor Shuang Zhang from The University of Hong Kong (HKU), along with National Center for Nanoscience and Technology, Imperial College ...

A quartz-lined waveguide kept terahertz light synchronized with relativistic electrons, pointing toward much smaller ...

A wave number, or wavenumber, refers to the spatial frequency of a wave over a specific unit distance. The wave number is measured either in cycles per unit distance or in radians per unit distance, ...

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations. While ...

Astronomers are on the verge of unlocking an entirely new way to observe the universe. Since the first detection of gravitational waves in October 2015, scientists have been listening in to these ...

For the first time, physicists have found what they are calling “compelling evidence” for low-frequency gravitational waves, ripples in space-time usually caused by massive cosmic objects orbiting ...

Whenever I find myself harboring a constantly nagging thought, I know I will eventually have to get busy and find a way to put it to rest. When I read EDN’s Design Ideas, I look for the range of ...
