Abstract:To determine the mechanical properties and morphology of solid materials, tomographic imaging at relatively low frequencies is a promising option. However, mode conversions between compressional and shear waves require the use of non-linear tomographic methods taking multiple scattering into account. For this reason, we presented an approach based on the Kaczmarz method. A necessary condition of convergence is that the accumulated phase difference between a wave propagating through the background medium and th… Show more
