Abstract
The nonlinear propagation of a lower hybrid (l.h.) disturbance in unif orm and nonuniform plasmas is computed, consistently with the finite a mplitude density modifications due to the ponderomotive forces origina ted by the radio frequency (r.f.) power itself. Strong spectral broade ning is shown to occur due to the coupling with magnetized acoustic wa ves. (C) 1997 Elsevier Science B.V.
