For the first time, scientists have managed to pick up higher harmonics accompanying the cosmic song that rings out through the universe. The LIGO and Virgo gravitational wave detectors have been ...

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

Abstract: Wave motion lies at the heart of many disciplines in the physical sciences and engineering. For example, problems and applications involving light, sound, heat, or fluid flow are all likely ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.200097 consider boosting second harmonic generation with TMDs monolayer via dual bound states in the continuum in a photonic ...

Metamaterials and metasurfaces have attracted great interests in recent years for their versatile possibilities in manipulating electromagnetic (EM) waves. Embedded tunable devices such as ...

[Levi Janssen] has a secret: he doesn’t like harmonic drives. But rather than abandon the torque-amplifying transmission completely, he decided to see about improving them using 3D-printed compliant ...
