Inverse scattering of an imperfectly conducting cylinder with corners by Firefly Algorithms

In this paper, the inverse scattering of an imperfectly conducting cylinder with corners is given by the Firefly Algorithm. The inverse problem is first transformed into a nonlinear optimization problem, and then solved by the Firefly Algorithm. To treat a target with corners, the target shape is modeled by the cubic spline interpolation. The Firefly Algorithm utilized in this study is a biologically inspired algorithm. It has been proved to be efficient with high success rate. Since the inverse scattering involves complicated computation, the Firefly Algorithm is a good candidate for reconstructing the target information.
