Opis:
In this study, the anomalous transmission of wave through over-dense magnetized plasma is investigated. Electromagnetic waves propagate in over-dense matter through an excitation of the surface waves. For excitation of the surface waves, the structure of the prism, dielectric and magnetized over-dense plasma are considered. Variations in the transmitted and reflected amplitudes with the incident angle θ is investigated. Moreover, the effect of the thicknesses of the dielectric and plasma layers and that of the plasma and cyclotron frequencies on the transmitted wave amplitude are studied. In addition, the Faraday rotation of the transmitted and reflected waves as functions of the incident angle is investigated. The effect of various parameters on the Faraday rotation is considered. The prism currently deployed in this structure decreases the restriction of dielectric constant and provides conditions for actual construction.

Opis:
A Bohm-type coefficient of diffusion is obtained by means of a procedure starting from the Hamiltonian of a single electron in a dilute plasma in the presence of an external, uniform magnetic field of constant magnitude and an electrical potential that serves to simulate an electrical fluctuation which drives the guiding center drift. Using the concept of the differentiation of operators with respect to time, the formula for the well-known E × B drift velocity is recovered. Finally, the solution of a quantum mechanical equation of motion for the guiding center is found in the quasi-classical approximation to obtain a diffusion coefficient.

Opis:
The research reported in an article previously published in this journal is pursued here further on. A staircase profile of the graphical representation of the absolute value of the expression for Bohm-type diffusion in two dimensions is analyzed allowing the suggestion that its shape could be related to the well-known structure of levels of the quantized square of the guiding center radius vector and that this structure could be responsible for the appearance of the successive steps in such a profile. When these considerations are taken into account, the expression for Bohm-type diffusion in two dimensions is normalized according to the formula for the quantized square of the guiding center radius vector and a diffusion coefficient whose value is 4/π times the Bohm diffusion coefficient is obtained for large values of the independent variable.
