In this chapter the inverse scattering problem was considered which belongs to the category of inverse problems, which includes many very challenging problems encountered in several applications, including atmospheric sounding, seismology, heat conduction, quantum theory, and medical imaging. From a strictly mathematical perspective, the definition of a problem as the inverse counterpart of a direct one is completely arbitrary. In imaging applications, one measures the scattered field and tries to obtain information on the object subjected to the incident radiation. Computation of the electromagnetic field scattered by arbitrarily shaped dielectric objects when they are illuminated by a generic incident field is a complex task that seldom can be performed by using analytic techniques. Microwave imaging techniques can in principle be applied to three - dimensional configurations without theoretical limitations, most of the approaches proposed so far in the scientific literature are still related to two - dimensional problems.
