Electrodynamic friction of a charged particle passing a conducting plate

We investigate the friction acting on a charged particle moving parallel to an imperfect conductor slab described with the Drude model. In nonrelativistic and ultrarelativistic regimes, the properties of frictions due to the TE and TM modes are quite different. The velocity dependence of the friction is non-monotonic. The friction may be nonzero in the low-resistivity limit when the particle is moving with a high velocity. Other properties of the friction are also studied
