| 摘要 | In this paper, we apply the DDE algorithm to solve the inverse scattering problem for which a two-dimensional (2-D) dielectric cylinder with unknown cross section is buried in a dielectric slab medium. Finite difference time domain method (FDTD) is used to solve the scattering electromagnetic wave of a dielectric cylinder. The inverse problem is resolved by an optimization approach and the global searching scheme dynamic differential evolution (DDE) is then employed to search the parameter space. By properly processing the scattered field, some EM properties can be reconstructed. One is the location of the dielectric cylinder; the others are the shape of the dielectric cylinder and permittivity of the dielectric cylinder. This method is tested by several numerical examples, and it is found that the performance of the DDE is robust for reconstructing the dielectric cylinder. Numerical simulations show that even when the measured scattered fields are contaminated with Gaussian noise, the quality of the reconstructed results obtained by the DDE algorithm is very good. |
