Abstract
Anomalous absorption of a lower hybrid wave via mode coupling to short parallel wavelength density fluctuations in a magnetized plasma is investigated. The mode coupling produces a beat mode with the frequency of the lower hybrid wave but an enhanced parallel wave number. This mode is Landau damped on electrons. The oscillatory velocity associated with the beat mode couples with the density ripple to modify the density perturbation of the lower hybrid wave introducing anomalous resistivity. The anomalous resistivity increases with the normalized wave number of the density ripple.
