Electromagnetic inverse scattering of axially moving elliptic targets

This paper shows that inverse scattering techniques can be successfully used to find the geometrical and constitutive parameters and the velocities of axially moving, inhomogeneous cylinders. For this reason, these techniques could be of interest in industrial applications or in plasma physics. In particular, the forward problem is solved by generalizing a semi-analytical recursive procedure developed for the computation of the field scattered by multilayer elliptic cylinders. The inverse problem is addressed by using a stochastic method based on the Artificial Bee Colony algorithm.
