Abstract
A new method based on steepest descent and topology evolution is presented to identify an unknown scatterer shape and physical property. Level set method is modified to not only evolve an arbitrary penetrable object shape but also retrieve its relative dielectric constant. Computation time is significantly reduced and accurate reconstruction is obtained. The method accuracy is illustrated by two examples.
