Energy flow and group velocity for longitudinal propagation,In a homogeneous collisionless magnetoplasma let us examine the storage and flow of energy that occurs when a circularly polarized characteristic wave of angular frequency co propagates along the imposed magnetic field. The propagation constant . is given in terms of the refractive index . by (Equation 2.50) .

The field of an antenna in a magnetoplasma,In the previous chapter we described the behaviour of the polar diagrams of group velocity for the . and . waves. In Chapter 18 we shall treat the polar diagrams of radiated power. For this purpose we deduce in this chapter expressions for the far field of an antenna located in a homogeneous magnetoplasma.

Alternating current in a magnetoplasma, oscillatory, is uniform in space. We are then considering a homogeneous plasma that is simultaneously subject to a uniform steady magnetic field of flux density .. and to a uniform electric field E that oscillates with angular frequency ω

Propagation of phase along the imposed magnetic field,ongitudinal propagation (.. = 0 or π). Because of the axial symmetry round the imposed magnetic field, the direction of group propagation is then the same as the direction of phase propagation (θ. = 0 or π); it may be verified from Equation (6.34) that, when .. = 0, we also have .. = 0. The magnitud

Elliptic polarization of the X wave for transverse propagation,nstitute a right-handed mutually perpendicular system of directions. For transverse propagation of the . wave, these vectors are linearly polarized as described in Section 9.3. The . vector of the wave vibrates linearly back and forth parallel to the imposed magnetic field, and the . vector vibrates
