Abstract
By using a guiding-center distribution function, an expression for Landau damping is derived for closed Fermi surfaces of arbitrary shape in the case where the cyclotron frequency is much greater than the collision frequency. It is shown that the strength of the damping is determined by the average over the cyclotron orbit of the power delivered by the wave to the resonant electrons. The resonant coupling can always be written as a sum of electric and magnetic contributions, but the damping in general cannot, because of interference effects.Keywords
