Effects of anisotropic parameter on the electrical conductivity by the helicon waves

To determine the propagation of helicon for such a metal we must calculate σsub(-). The expression for σsub(-) in a static magnetic field of the electrons in metal is obtained by the semiclassical method. We study that part of anisotropic effects expressed by relaxation-time of four-fold symmetry on the helicon propagation along the symmetry axis. From the result, we found that the effects of anisotropic parameter were contribution from the first order in the conductivity, and the second order effects are presented in a sufficiently strong magnetic field.
