Numerical simulation in diffraction tomography with elastic and electromagnetic sounding signals
The results of numerical simulation on restoration of parameters of local in-homogeneities are considered. Studying of restoration of elastic inhomogeneities and inhomogeneities of electrical conductivity is implemented using elastic and electromagnetic wave fields correspondingly. The direct problem for the Lame and Maxwell equations is solved by the finite difference method. Restoration of parameters is implemented by the diffraction tomography method in the time domain with the help of the first-order Born approximation. In electromagnetic case we study restoration of local inhomogeneity of electrical conductivity using the sounding by diffusion electromagnetic field.
