The general problem of electromagnetic wave scattering by thin inhomogeneous circular cylinders is completely formulated. An integral equation for the induced axial current distribution is derived and solved for an incident plane wave of arbitrary direction of propagation. A knowledge of this induced current allows the determination of the scattered fields as well as the scattering cross section. For convenience the conductivity is only considered to vary axially. Numerical results are presented for the induced axial current and scattering cross section. An important application of this work is in missile vulnerability studies. To this end numerical results are presented for a missile having an ionized exhaust trail. The conductivity of the exhaust trail is considered to taper exponentially along its axis.
