Abstract

Lower hybrid wave propagation is studied for a general magnetic field configuration. The ray-tracing equations in the geometric optics approximation are solved analytically and numerically in flux surface coordinates by using asymptotic techniques. Particular emphasis is placed on the effects of elongation, triangularity and Shafranov-shift on the wave penetration. Numerical applications devoted to the study of current drive generation for ITER plasma parameters are also presented.
