Scattering from a moving cylinder: Oblique incidence

The scattering of plane waves from a moving perfectly conducting cylinder is treated in the general case of arbitrary velocity and oblique incidence. This is a generalization of the cases previously treated in the literature and includes discussion of an additional phenomenon, mode coupling, which does not occur in the cases treated previously. Attention is focused on the depolarized component of the scattered field as it is one of the more apparent manifestations of the mode coupling. In addition, Doppler shift is discussed, and scattered power is calculated in the far fields of a thin wire. It is shown that, to first order in β = v/c, Doppler shift depends only on the component of velocity which is perpendicular to the cylinder and in the plane of incidence and that an azimuthal component of scattered power exists which does not occur in the absence of motion. The treatment is relativistically correct.
