Using the Langevin approach and the multiscale technique, a kinetic theory of the time and space nonlocal fluctuations in the collisional plasma is constructed. In local equilibrium a generalized version of the CallenWelton theorem is derived. It is shown that not only the dissipation but also the time and space derivatives of the dispersion determine the amplitude and the width of the spectrum...

We present a method for automatic segmentation of grey-scale images, based on a recently introduced deformable model, the charged-particle model (CPM). The model is inspired by classical electrodynamics and is based on a simulation of charged particles moving in an electrostatic field. The charges are attracted towards the contours of the objects of interest by an electrostatic field, whose sou...

The invisibility cloak has been drawing much attention due to its new concept for manipulating many physical fields, from oscillating wave fields (electromagnetic, acoustic and elastic) to static magnetic fields, dc electric fields, and diffusive fields. Here, an electrostatic field invisibility cloak has been theoretically investigated and experimentally demonstrated to perfectly hide two dime...

We have decelerated a supersonic beam of 174YbF molecules using a switched sequence of electrostatic field gradients. These molecules are 7 times heavier than any previously decelerated. An alternating gradient structure allows us to decelerate and focus the molecules in their ground state. We show that the decelerator exhibits the axial and transverse stability required to bring the molecules ...

We numerically investigated the ion behavior in radio frequency (RF) plasma with a pulsed magnetic field applied to high-current source. A one-dimensional hybrid particle-in-cell (PIC) simulation was performed. The numerical results demonstrate generation process of an beam by applying RF plasma. induces electric owing interaction between and field. induced forms density gradient, electrostatic...

A new method to measure the internal magnetic field in a plasma, based on crosscorrelation of ordinary (O) mode and extraordinary (X) mode reflectometer signals originating from naturally occurring turbulence, is investigated. This method relies on identifying the Oand X-mode frequency pair (fo, fx) where cross-correlation is maximum. Maximum cross-correlation is found to occur at an X-mode fre...

The effects of different boundary conditions on Alfvén wave dynamics in reduced magnetohydrodynamics are described. If one assumes that the derivative or the second derivative of the electrostatic potential is zero at one of the radial across the magnetic field boundaries, radially localized guided Alfvén wave solutions are possible, but if is set to zero grounded at both boundaries, the soluti...
