We study the motion of free masses subject to influence standing gravitational waves in polarized Gowdy cosmology with a three-torus topology. show that antinodes attract freely falling particles and we trace velocity memory effect.

Due to economic social cohesion, the European Union is promoting to improve the production of electrical energy from renewable energy sources. Sea waves have associated a form of renewable energy which can be captured by using a hydro mechanical device that in turn drives an electrical generator to produce electrical energy. After a brief description of wave formation and quantifying the power ...

When capacitively coupled plasma (CCP) is used to generate large-area plasma, the standing wave effect becomes significant, which results in the hindering of the uniform plasma process such as in a plasma etcher or plasma chemical vapor deposition. In this study, the transmission line modeling method is applied to calculate the voltage distribution over atmospheric-pressure CCP electrodes with ...

We report on three-dimensional optical trapping of single ions in a one-dimensional optical lattice formed by two counterpropagating laser beams. We characterize the trapping parameters of the standing-wave using the ion as a sensor stored in a hybrid trap consisting of a radio-frequency (rf), a dc, and the optical potential. When loading ions directly from the rf into the standing-wave trap, w...

Theoretical aspects of x-ray standing wave method for investigation of the real structure of crystals are considered in this review paper. Starting from the general approach of the secondary radiation yield from deformed crystals this theory is applied to different concreate cases. Various models of deformed crystals like: bicrystal model, multilayer model, crystals with extended deformation fi...

The velocity fields of acoustic standing wave in a rectangular channel are investigated. A new approach is used to measure the velocity fields using PIV. In this approach, the velocity fields are sampled at different phases in a given experimental run without synchronizing the PIV system with the excitation signal. The results show that the RMS velocities measured from this approach are in exce...

This paper is concerned with the existence and qualitative property of standing wave solutions (t; x) = e ?iEt=~ v(x) for the nonlinear Schrr odinger equation ~ @ @t + ~ 2 2 ? V (x) + jj p?1 = 0 with E being a critical frequency in the sense that min R N V (x) = E. We show that there exists a standing wave which is trapped in a neighborhood of isolated minimum points of V and whose amplitude go...
