Mode-switching and nonlinear effects in supersonic jet noise
AIP Advances, 2018 The paper employs STFT (Short Time Fourier Transform) to extract and analyze the noise components of a supersonic jet through four rectangular nozzles with different AR (Aspect Ratio) since it can capture and represent the evolution of screech and its ...

Microwave photoresistance in a two-dimensional electron gas with separated Landau levels
, 2011 Theories of microwave-induced resistance oscillations in high-mobility two-dimensional electron gas predict that with decreasing oscillation order $n$ or with increasing frequency $\omega$ the photoresistance maxima should appear closer to the cyclotron ...

Harmonic analysis of AC-bus voltage in converter station based on time–frequency transformation
The Journal of Engineering, 2018 The disturbance of the AC system has become one of the main causes of commutation failure in the high voltage direct current (HVDC) transmission system. Here, the time–frequency transformation method is used to analyse the AC-bus voltage disturbance from

Magnetic mirror cavities as THz radiation sources and a means of quantifying radiation friction
, 2014 We propose a radiation source based on a magnetic mirror cavity. Relativistic electrons are simulated entering the cavity and their trajectories and resulting emission spectra are calculated.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Observable effects caused by vacuum pair creation in the field of high-power optical lasers
, 2007 We consider the possibility of an experimental proof of vacuum e+e- pair creation in the focus of two counter-propagating optical laser beams with an intensity of the order of 10^20 - 10^22 W/cm^2.
