Contrast Source Inversion Method Using Multi-Frequency Data

摘要

A method for reconstructing the complex permittivity of a bounded inhomogeneous211u001eobject from measured scattered field data is presented. In this work we apply the 211u001eContrast Source Inversion (CCI) method to the experiment in which multi-frequency 211u001edata are available, inspired by the success of the CSI method in case of single-211u001efrequency data (PB99-1765323) and (PB96-203658) and the results of the multi-211u001efrequency approach in Modified Gradient techniques.
