摘要

We discuss a one-dimensional inverse problem of electromagnetic wave transmission through a layered dielec-tric structure which is to be identified from the transmission coefficient absolute values for a plane wave of normal incidence measured in a bounded frequency bandwidth. A reason for nonuniqueness in the inverse γroblem of recovering the unknown structure parameters is explained. Methode of measurement and data processing are suggested that allows to uniquely identify the structure parameters based on frequency depen-dence of absolute values of transmission coefficients obtained in two separate experiments using a reference dielectric slab.
