摘要This paper presents a computational approach to the transverse electric (TE) wave imaging of an imperfectly conducting cylinder. An imperfectly conducting cylinder of unknown shape and conductivity scatters the incident TE wave in the free space, and the scattered field is recorded outside the object. Based on the boundary condition and measured scattered field, a set of nonlinear integral equations is derived and the imaging problem is reformulated into an optimization one that solved by steady-state genetic algorithms. Numerical results demonstrated that, even when the initial guess is far away from the exact one, good reconstruction for shape and conductivity of the object can be obtained. In addition, the effect of noise on reconstructed results is also investigated.
