On the theory of electromagnetic surface waves in magnetized semiconductor plasma

Abstract

The paper demonstrates existence of electromagnetic surface waves at the boundary separating a magnetized semiconductor plasma and a dielectric or metal. The external magnetic field is along the interface. As has been shown, slow surface waves of the helicon or Alfven type can exist only with their propagation vector directed obliquely with respect to the magnetic field. The ω- k relations have been found and ranges of existence established both in the frequency domain and that of angles between the propagation vector and the magnetic field.
