In this series of papers, we propose a method for constructing an approximate solution of the Maxwell equations in smoothly inhomogeneous anisotropic gyrotropic media with allowance for aberrations, spatial dispersion, and absorption. Evolution equations for wave beams are obtained and a method for their numerical solution is developed. Their relation to equations of the nonaberrational approximation is shown. In this second part, we derive a quasioptical evolution equation for wave beams and propose a method for its numerical solution. The connection with the aberration-free approximation equations is shown.
