Abstract :
A method for reconstructing the complex permittivity of a bounded inhomogeneous object from measured scattered field data is presented. We apply the contrast source inversion (CSI) method to the experiment in which multi-frequency data are available, inspired by the success of the CSI method in case of single-frequency data. The scattering object is considered to be an inhomogeneous lossy dielectric cylinder of arbitrary cross-section embedded in a bounded domain of free space.
