| چکیده | ||
| This research investigated the formation of surface waves on a cold semiconductor plasma structure and the way electromagnetic waves pass in the presence of a magnetic field. The main mechanism of the passage of electromagnetic waves through dense plasma was analyzed, ignoring collisions, attenuation, and the effects of the reflection coefficient of electromagnetic waves. The cold semiconductor plasma is opaque to the passage of electromagnetic waves, and only under special conditions of resonance stimulation of surface waves, this plasma can act like a transparent object against these waves. After considering the specific structure of the plasma and defining the basic relations, it will be shown that the passage of the electromagnetic wave through it occurs due to the excitation of the plasma surface states. It was deduced from the relationships that the intensities are maximum at the boundaries, on the plasma surfaces, which indicates the creation of surface states. The wave transmission inside the desired magnetic semiconductor plasma layer occurs due to these surface states. On the other hand, for waves with a lower inclination angle, the amount of electromagnetic wave passing through this material increases. This means that in lower angles, the turbid plasma becomes a transparent medium that can function by transmitting high-wavelength energy through it. It is emphasized that only the normal state was analyzed in this research. Since surface waves can be excited on both sides of the plasma, this structure can be very efficient for fabricating super-lenses, and the introduced structure facilitates the passage of conventional electromagnetic waves through dense semiconductor plasma. In this particular case, it was observed that the external magnetic field does not affect the wave propagation because there is no effect of the magnetic field on the relationships. | ||
