Particle-In-Cell (kinetic) simulations of shear Alfv\'en wave interactionwith one dimensional, across the uniform magnetic field, density inhomogeneity(phase mixing) in collisionless plasma were performed for the first time. As aresult a new electron acceleration mechanism is discovered. Progressivedistortion of Alfv\'en wave front, due to the differences in local Alfv\'enspeed, generates nearly parallel to the magnetic field electrostatic fields,which accelerate electrons via Landau damping. Surprisingly, amplitude decaylaw in the inhomogeneous regions, in the kinetic regime, is the same as in theMHD approximation described by Heyvaerts and Priest (1983).
