The bulk and surface helicons in the regularly inhomogeneous semiconductor structure

In this paper the surface waves propagated along the contact of two periodic semiconductor lattices placed in the external magnetic field is considered. Magnetic field vector is situated in the same plane where electromagnetic waves propagate. Parameterspsila region is investigated where the helicon waves propagate. The distinctive feature of the helicon wave spectrum is that the numerous narrow allowed zones arise. It is shown that near the edge of the bulk helicon transmission band the surface helicon wave exist.
