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 ...

Designed for three-phase power electronics with 6-pulse rectifier front ends — such as ac and dc motor drives — the ECOsineT load-applied passive power quality filters tame harmonic waves. Total ...

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 research team identifies second-harmonics generation interference in 2D heterobilayers. Since the invention of world's first laser -- the ruby laser -- in 1960, the human desire to control light has ...

There are several ways to evaluate the bandwidth of a signal in the time domain and frequency domain. Previously we looked at the classic relationship of rise time (t r) and bandwidth (f 3db) [Ref 1], ...
