Abstract: With high-proportion power electronic converters penetrating AC grid, high-frequency oscillations of AC voltage and current are frequently observed during system dynamics. The ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. The amplitude (\(a\)) of a wave is the distance from the centre ...

Abstract: The recently proposed orthogonal time frequency space (OTFS) modulation, a representative delay-Doppler (DD) communication scheme, has demonstrated appealing performance over ...

A compact aperture-adjustable antenna developed by researchers at Science Tokyo could improve high-speed wireless communication across the wide 5G millimeter-wave frequency bands without increasing ...
