Propagation of TE-Surface Waves on Semi-Bounded Quantum Plasma

Abstract

The propagation of the TE-surface waves on a semibounded quantum plasma is investigated by using the system of generalized quantum hydrodynamic (QHD) model and Maxwell's equations. The dispersion relations for these surface waves on quantum electron plasma in the presence of external magnetic field which is parallel to the wave propagation are derived. The perturbation of electron density and the electric fields of the TE-surface waves are also obtained. However, it was found that quantum effects (Bohm potential and statistical) have no remarkable action on the electric and magnetic field components in the case of unmagnetized plasma. But, it was found that the dispersion relation of surface modes depends significantly on these effects in the case of electrostatic or unmagnetized plasma.

Spin effect on propagation of surface waves in a magneto‐active quantum plasma

“…The instability of surface waves was studied by Shokri and Rukhadze in a single-and double-component quantum plasma. [21,22] Excitation of Transverse Magnetic (TM) surface waves in magnetized spin quantum plasmas was also studied by Mohamed, and he used an approximate method to obtain dispersion relation; therefore, the importance of the spin effect is not clearly shown in his results. Moreover, Mohamed studied the behaviour of Transverse Electric (TE) surface waves in both magnetized and unmagnetized quantum plasma half-space and demonstrated the significant effect of external magnetic field on the surface waves.…”

High-Frequency Electrostatic SW at the Boundary between Quantum Plasma and Metal

“…Lazer et al [15] has presented the dispersion relation for surface plasmons that can exist on a dense quantum plasma half-space. Also, Mohamed [16] studied the quantum effects on the propagation of electromagnetic surface waves in magnetized and unmagnetized plasma and got the dispersion relations for TM-(and TE- [17]) polarized surface modes.…”

Comment on “Propagation of a TE surface mode in a relativistic electron beam–quantum plasma system” [Phys. Lett. A 376 (2012) 169]

“…Recently, Mohamed and Abdel Aziz [1], studied the propagation of the TE surface waves on the semi-bounded magnetized quantum plasma in the Faraday configuration (in this case the magnetic field is parallel to the both of the plasma surface and direction of propagation). Then, Abdel Aziz [2] extended the results obtained in Ref.…”
