Abstract
A two-step Marchenko inversion method is presented for samples mounted on a thick substrate, representing the substrate by a background pote ntial. The inversion for complex potentials is discussed in regard to the Elimination of negative wave numbers and the phase problem. The ef fect of a wave number cut-off in reflectivity measurements is illustra ted.
