The effects on the missile skin current due to the presence of an exhaust plume are studied via analyzing thin-wire and body-of-revolution models of the missileplume configuration. In the wire model, the simple and efficient thin wire theory and numerical methods are used to estimate order of magnitude effects by treating the missile as a thin cylinder and the plume as an attached lossy cylinder. Several body-of-revolution models are also described, compared and used to analyze large radius plumes modeled both as homogeneous and inhomogeneous bodies-of-revolution. Extensive results are presented for all models to permit one to compare the differences in currents induced on the missile with and without the plume as functions of frequency, incidence angle of the plane wave source, plume conductivity, and plume shape.
