  AbstractIt has been shown that the overdense plasma in the resonance conditions can be totally transparent to the incident electromagnetic waves, due to the excitation of the surface modes or plasmons. This scenario requires excitation of a single surface mode which is provided by placing a dielectric layer in front of the incident wave. Here, it is shown that this procedure would be complete and more efficient by arranging the conditions to excite coupled surface modes, namely by placing two dielectrics on both sides of the plasma layer. The results show that in this case, the overdense plasma slab could poses high transmittance in spite of the presence of the dissipative effects. In addition, in this case, the resonance conditions can be achieved more easily and efficiently, and can be used for wider range of the overdense plasma widths. پرونده مقاله

  AbstractThe dominant procedure for the transmission of electromagnetic waves on an over-dense plasma layer is the excitation of surface waves. The conditions for this wave excitation on the surface of over-dense plasma, hence, become important. Here, the dispersion relation for the surface wave excitation on an over-dense plasma medium which is exposed to a magnetic field is studied. These investigations lead to the condition required for producing the surface waves. By this dispersion condition, an analytical function for the wave vector in terms of the phase velocity and the cyclotron and collision frequencies is established. Specifically, the outgoings of these dependencies and also the condition for exciting more stable waves are discussed. پرونده مقاله
