In this paper, we applied the Born Iterative Method (BIM) to reconstruct three-dimensional inhomogeneous objects buried in spherically multilayered media. The nonlinear inverse problem is linearized by Born approximations and solved iteratively via the conjugate-gradient approach (CG). The forward scattering problem in the spherically multilayered media is solved by stabilized biconjugate-gradient...
In this paper, we applied the electromagnetic forward and inverse scattering algorithms to planarly layered dispersive plasma media. The media have four layers with different plasma frequency in each layer. The disturbed region is located in layer 2, and takes effect as an electromagnetic wave scatterer. We use the stabilized biconjugate gradient fast Fourier transform (BCGS-FFT) method to compute...
The dyadic Green's function (DGF) method is widely used for the calculation of electromagnetic forward and inverse scattering in unbounded media, layered media, anisotropic media, etc. The forward scattering volume integral equations are usually solved by iteratively updating the total electric fields inside the inversion domain. In this process, the Green's functions for source and field points both...
