Doubly Excited Slab-Shaped Magneto-Plasma with the Help of the Lines of Magnetic Currents

Abstract

The excitation of solid semiconductor plasma and gaseous plasma with the two magnetic line sources (having similar and dissimilar frequencies) has been studied while magnetic field is present in the direction parallel to that of line sources. The amplitude of the radiation field has some interesting features while considering the changes in a, ν/ω, ω_ν/ω and ω,/ω for both the plasmas. For different a values in almost all the cases, one intense peak is followed by other less intense peaks. Radiation peaks obtained for lossless plasma get their magnitudes reduced when lossy behaviour of plasmas is taken into account. The change in a affects the direction and magnitudes of radiation peaks for lossy and lossless plasmas. Considering the dissimilarity of the source frequencies, the 0° radiations (for semiconductor) attain the maximum for a particular difference in two source frequencies having less amplitude before and after the maximum radiation. The dissimilarity, in case of geseous plasma gives the oscillating nature of 0° radiations having more amplitude of radiation against the increase in one of the source frequencies.
