Quantum kinetic theory and the Image Particle Method are introduced to simulate charged particle fluxes, which allow to include effects of generated electric and magnetic fields in addition to all previous results for charged particle flows simulations in external electromagnetic fields. A gauge invariant Wigner function has been introduced in this paper for kinetic simulation of wakes, disturbances in plasma with formulation in terms of general electro-magnetic fields. This Wigner formulation is the natural language to describe quantum transport, and to monitor decoherence of macroscopic quantum states in interaction with the environment. According to this new “Image Particle Method”, the collision integrals, corresponding simulated collision operators for these “image particles” describe the effects from the generated electric and magnetic fields.

This exact expression is based on the obtained distribution function as analytical solution for Boltzmann equation for charged particle flows in magnetic field. This can be considered as a saturation phenomenon, when we see significant slow-down of the heat flow increase versus the magnetic field still increasing at the same rate. It is instrumental when we need to estimate the saturation maximum of the heat flow, when we have the only 1 parameter to change: magnetic field.

The model Boltzmann equation is solved, taking into account interparticle collisions in plasma, interactions with ambient neutral particles and effects of external magnetic fields. Using this solution the analytical and numerical results are obtained which describe developing magnetic field aligned stratifications of plasma flows in Space and the upper ionosphere. For magnetic field aligned drifting velocity of the plasma flows, formation of flute structures along the edges of the flows is obtained analytically and numerically. Using the image method ([1]-[3]) the wakes of different objects in the ionosphere and Space are simulated. Different kinds of interactions of the ambient particles with object surfaces are considered as absorption, direct and diffuse reflection. The results describe the flute structure of wakes of objects in motion along the external magnetic fields and stratifications of wakes in different cases.

A primary wave is launched obliquely with respect to the magnetic field and a secondary, low amplitude, wave is launched perpendicularly. The effect of both the launching angle of the primary wave, and the presence of the secondary wave is investigated. Theoretical predictions of the highest performances of the three-dimensional (3D) configurations are proposed using a Resonance Moments Method (RMM) based on estimates for the moments of the velocity distribution function calculated inside the resonance layers (RL). They suggest the existence of an optimal angle corresponding to non parallel launching. Direct statistical simulations show that it is possible to rise the mean electron velocity up to the order of magnitude as compared to the primary wave launching alone. It is a quite promising result because the amplitude ...

The idea is to launch low amplitude secondary waves in order to improve the parallel momentum transfer from the high amplitude primary wave to the charged particles. The use of two parallel counter-propagating waves has recently been considered and numerical tests have shown that the two-wave scheme may lead to higher averaged parallel velocity [1,2]. On the other hand in Refs. [3,4] it has been concluded that it is more effective to accelerate electrons when the waves propagate obliquely to the external magnetic field. The majority of the existing works are based on the description of a single particle dynamics in one (or more but under condition of equality of their parallel refractive indexes) plane monochromatic radio frequency waves. In this paper, a mechanism is discussed for the acceler...

The image method (see [1], [2]) is considered in application to modeling disturbances of space plasma. The specific case of diffuse reflection of any particle impinging on the object surface is simulated in detail. As applications of the method, simple analytical expressions have been obtained for the far disturbances of the ion concentration due to the diffuse reflecting plate motion at an arbitrary angle to the ambient magnetic field. Different directions of the motion with respect to the plate normal are considered. Disturbances of charged particle concentration are calculated using numerical and analytical methods. The surfaces of constant disturbances are plotted. This work with previous author's results allow the following conclusions: (i) both different interactions with surfaces and ambient electric, magnetic fields can have strong impacts on disturbances due to moving surfaces (ii) these impacts are simulated by kinetic equations which can be solved by numerically and in some specific cases analytically.
