Damping of a moving particle near a wall: A relativistic approach - art. no. 035403

The movement of a small particle near a wall, characterized by any dielectr ic function, was considered on the basis of relativistic and fluctuating el ectrodynamics. A friction coefficient, due to the dissipation of the energy of the relative motion originating from thermal fluctuating electromagneti c fields, was obtained as a power series of the inverse shortest distance b etween interacting bodies. Possible manifestations of image enhancement eff ects in damping, leading to giant Raman scattering, are discussed.
