Chiral standing spin waves in skyrmion lattice
APL Materials, 2022 This work studies the resonance excitations of the three-dimensional skyrmions lattice in the finite thickness plate of an isotropic chiral magnet using spin dynamics simulations. We found that the absorption spectra and resonance modes differ from those

The Periodic Standing-Wave Approximation: Overview and Three Dimensional Scalar Models [PDF]
, 2003 The periodic standing-wave method for binary inspiral computes the exact numerical solution for periodic binary motion with standing gravitational waves, and uses it as an approximation to slow binary inspiral with outgoing waves.

Optics Express, 2010 A standing wave Fourier transform spectrometer is realized. The spectrometer consists of an ultra thin and partially transparent photodetector and a tunable mirror. The incident light forms a standing wave in front of the mirror, which is sampled by the ultra thin optical detector.

Impact of Nonlinear Standing Waves Underneath a Deck [PDF]
Archives of Civil Engineering, 2020 A theoretical approach was applied to investigate the impact of nonlinear standing waves underneath a horizontal deck. A solution was achieved by applying a boundary element method. The model was applied to predict impact pressure underneath a deck.

Orbital instability of standing waves for NLS equation on star graphs [PDF]
Proceedings of the American Mathematical Society, 2017 We consider a nonlinear Schrodinger (NLS) equation with any positive power nonlinearity on a star graph $\Gamma$ ($N$ half-lines glued at the common vertex) with a $\delta$ interaction at the vertex.

Correction of evanescent wave influence on the flexural wave velocity and wavelength estimation based on a mode shape function [PDF]
Archives of Acoustics, 2022 The aim of this research is to use a simple acoustic method of a very near field recording, which enables measurement and display of oscillation modes, to estimate the velocity of flexural waves, based on the wavelengths of standing waves measured on the

Orbital stability of standing waves for a system of nonlinear Schrödinger equations with three wave interaction [PDF]
, 2017 We study the existence and stability of standing waves solutions of a three-coupled nonlinear Schrodinger system related to the Raman amplification in a plasma.

Experimental study of local scour around diamond bridge piers subject to transverse standing waves
Ain Shams Engineering Journal, 2022 Numerous bridges around the world have been destroyed due to local scour around their piers and abutments. Transverse standing waves (perpendicular to the flow direction) generated by obstacles, such as bridge piers, can affect the extent of local scour ...
