Biological tissues like breasts are dispersive inhomogeneous dielectric objects and microwave imaging for them can be formulated by volume integral equations (VIEs). The distorted Born iterative method (DBIM) is used to reconstruct the objects in recent years, but it requires to update the dyadic Green's function in each iteration and is also sensitive to the initial guess of object property. We use...
Reconstructing unknown dielectric objects by integral equation approach (IEA) requires to alternatively solve the forward scattering integral equation (FSIE) and the inverse scattering integral equation (ISIE) in the frame of Born iterative method (BIM) or its variations. Though the FSIE can be conveniently solved with regular numerical methods, solving the ISIE could be challenging because of its...
