Abstract :
Linear sampling method (LSM) is a simple and effective method for reconstruction of unknown objects shape. It is also a fast and reliable method for finding the location of an object. This method is based on far field operator which relates the far field radiation to its associated line source in the object. There has been an extensive research on different aspects of the method. But from the experimental point of view there has been little research especially on the effect of polarization on the imaging quality of the method. In this paper, we study the effect of polarization on the quality of shape reconstruction in two dimensional targets. Examples comparing two different types of polarizations Transverse Electric (TE) and Transverse Magnetic (TM) on reconstruction quality of penetrable and non-penetrable objects is provided.
