Abstract: (879 Views)
In this paper, the resonance absorption due to the propagation of the electromagnetic wave with p-polarization in inhomogeneous warm plasma is investigated. Using Maxwell's equations, the electric field and magnetic field equations in the plasma were obtained. By separating the electric field of the wave into two parts, transverse and longitudinal, the distribution of the fields in three regions and the absorption rate curve were plotted. The results show that the resonance absorption reaches its maximum value at a certain angle and this angle changes with the change of plasma and laser beam properties. The results also show that increasing the temperature, increases the adsorption rate and plasma inhomogeneity also changes the distribution of electromagnetic fields and the absorption coefficient.
