Propagation of a Gaussian beam in a nonhomogeneous plasma [report]

1989 unpublished
The asymptotic theory of Choudhary and Felsen [IEEE Trans. Ant. Prop. AP-21, 827 (1973)] on the propagation of scalar inhomogeneous waves in twodimensional isotropic media is extended to the case of three-dimensional vector fields. The theory is applied to the propagation of Gaussian beams in nonhomoge neous media. The wave trajectory equations are then reformulated for anisotropic media and used for tracking a Gaussian beam in a tokamak plasma.
