Macroscopic and Microscopic Structure of Electromagnetic Wakefield
نویسنده
چکیده
Applying various stimuli to excite large-amplitude electrostatic structure within plasmas is a basic idea of plasma-based acceleration. However, because these stimuli are usually magnetized, whether or not their wakes within plasmas are purely electrostatic should be cautiously treated. By strict theory on self-consistent fields of charged particles, we make detailed investigations on the wakes of those magnetized stimuli and the acceleration by electromagnetic wakes. Keyowrds: Plasma wakefield.

One of the interesting Laser-Plasma phenomena, when the laser power is high and ultra intense, is the generation of large amplitude plasma waves (Wakefield) and electron acceleration. An intense electromagnetic laser pulse can create plasma oscillations through the action of the nonlinear pondermotive force. electrons trapped in the wake can be accelerated to high energies, more than 1 TW. Of t...
متن کاملCellular Automata Simulation of a Bistable Reaction-Diffusion System: Microscopic and Macroscopic Approaches
The Cellular Automata method has been used to simulate the pattern formation of the Schlögl model as a bistable Reaction-Diffusion System. Both microscopic and macroscopic Cellular Automata approaches have been considered and two different methods for obtaining the probabilities in the microscopic approach have been mentioned. The results show the tendency of the system towards the more sta...
متن کاملMolecular Identification of Macroscopic And Microscopic Cysts of Sarcocystis in Sheep in North Khorasan Province, Iran
Sarcocystis is an obligatory intracellular protozoan parasite which can infect humans and animals. Sheep are intermediate hosts of four Sarcocystis species: Sarcocystis tenella, Sarcocystis gigantea, Sarcocystis arieticanis, and Sarcocystis medusiformision. The purpose of the study was to determine the molecular identification of the macroscopic and microscopic cysts of Sarcocystis in sh...
متن کاملA “v2-f Based” Macroscopic K-Ε Model for Turbulent Flow through Porous Media
In this paper a new macroscopic k-ε model is developed and validated for turbulent flow through porous media for a wide range of porosities. The morphology of porous media is simulated by a periodic array of square cylinders. In the first step, calculations based on microscopic v2 − f model are conducted using a Galerkin/Least-Squares finite element formulation, employing equalorder bilinear ve...
متن کاملElectromagnetic Stress and Momentum in Matter
Whether the momentum density associated with an electromagnetic wave in a refracting medium is solely determined by its intensity or is dependent on the refractive index is perhaps of little practical importance, and probably beyond the power of present experimental techniques to decide. Nevertheless, since this question was first propounded by Abraham and Minkowski. it has continued to attract...
