Full-wave Inversion and Antenna Modeling for the Characterization of Cylindrical Targets

The reconstruction of the geometric and dielectric properties of unknown targets starting from measurements of the electromagnetic fields they scatter is essential in many different applicative areas, ranging from object detection in subsurface regions [1] to the recent developments related to biomedical and environmental engineering [2]. To obtain such information, an inverse problem should be solved, in which the unknown is represented by the characteristics of the objects. To this end, proper algorithms should be devised, specifically tuned for the measurement setup used for the inspection and for the target configuration
