A new integral-equation-based numerical approach to microwave imaging is presented. It can be applied to focused imaging in the sense that only one part of an inhomogeneous body is viewed as an unknown scatterer to be reconstructed. This approach is of great usefulness in many applications, as it results in a notable computational saving and in high flexibility. Moreover, it allows the range of applicability of the Born approximation to be considerably expanded.

Abstract
A new integral-equation-based numerical approach to microwave imaging is presented. It can be applied to focused imaging in the sense that only one part of an inhomogeneous body is viewed as an unknown scatterer to be reconstructed. This approach is of great usefulness in many applications, as it results in a notable computational saving and in high flexibility. Moreover, it allows the range of applicability of the Born approximation to be considerably expanded.
