  • Green's function;
  • microwave imaging;
  • tomographic configurations


The most ambitious goal of the inspection is to obtain complete images of the objects under test. Such images, when using microwaves, are directly related to the spatial distributions of the dielectric parameters of the scattering targets. This chapter discusses the most common configurations used in microwave imaging systems, with particular focus on the assumption made regarding measurement points and illumination conditions. Tomographic configurations are presented in detail for their significant practical relevance. However, scanning configurations are also considered. The chapter also describes the most frequently used approximations for simplyfing, when possible, the scattering equations. Finally, the problem of numerical computation of Green's function for arbitrary inhomogeneous background is discussed.
