| Abstract(in English) | This article considers the performance improvement of a reconstruction algorithm of estimating the relative permittivity of a lossy dielectric cylinder based on the multigrid optimization method. The inverse scattering problem can be treated as an optimization problem where the relative permittivity is determined by the minimization of a cost functional concerning the scattered electric fields measured and calculated. The multigrid optimization method consists of the modified frequency-hopping technique with a weighting factor, the multigrid method with a V-cycle, and the conjugate gradient method. Computer simulations are performed for lossy dielectric circular cylinders in free space to show the effect of the weighting factor on the reconstruction accuracy. |
