Abstract

The authors recently presented a novel microwave tomog- raphy method for creating quantitative images of the electromagnetic properties of the interior of unknown objects (1). This method is based on a time-domain inverse solver which uses the multi-illumination tech- nique and includes the dispersive and heterogeneous characteristic of the object. The Frequency Dependent Finite Difierence Time Domain ((FD) 2 TD) and Genetic Algorithm (GA) technique were utilized for determining unknown characteristics of the object. In the present pa- per, the calibration of measured data are described and image recon- struction results for preliminary experiments performed at the Uni- versity of Manitoba's Microwave Tomography Laboratory and at the Institut Frsenel are presented.
