Steady-state current drive in a plasma by lower-hybrid waves with a square-wave spectrum is analyzed in the linear approximation. A linearized two-dimensional kinetic equation in velocity space for the electron distribution function is reduced to a one-dimensional expansion in Legendre polynomials. A numerical solution is found for the complete equation, and an analytic solution is found for the asymptotic equation. The results can be used to determine the effect of the spectral width of the excited waves on the efficiency of the current drive. The analytic solution agrees well with the numerical solution.
