| Abstract: | In this paper, we presnet a new method for improving Born iterative method -the frequency coniensation technique. The frequency compensation technique is used to solve nonlinear inverse scattering problem for two-dimensional lossless dielectric inho-mogeneity using time-domain data. We use the transmitting boundary condition and the superabsorption technique in FDTD to reduce the error of scattering fields. |
