Excitation of Transverse Extraordinary Mode in an Inhomogeneous Magnetoplasma

Abstract

The extraordinary waves in an inhomogeneous magnetoplasma are studied. These waves are excited between the upper hybrid (ω_p²(r)=ω²−ω_c²) and the left hand cutoff (ω_p²(r)=ω²+ωω_c). The extraordinary waves propagate from the left hand cutoff point to the upper hybrid point perpendicularly to the static magnetic field lines of forces, so that the extraordinary waves are not excited near the upper hybrid but near the cutoff.
