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 ...

Frequency selective surfaces (FSSs) have widely been studied in the literature over the years 1,2,3,4,5. They are periodic resonant structures that selectively allow or prevent the transmission of ...

Second harmonic generation is the lowest-order wave-wave nonlinear interaction occurring in, e.g., optical, radio, and magnetohydrodynamic systems. As a prototype behavior of waves, second harmonic ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection experiments could function as highly precise gravitational wave detectors, thereby ...

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 ...

Millimeter wave imaging currently uses radio waves in the frequency range of 24-30 gigahertz (GHz). The advantage of this frequency range for personnel screening is that the waves can pass ...

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 ...
