  This paper addresses the electromagnetic inverse scattering problem of
determining the location and shape of anisotropic objects from near-field data.
We investigate both cases involving the Helmholtz equation and Maxwell's
equations for this inverse problem. Our study focuses on developing efficient
imaging functionals that enable a fast and stable recovery of the anisotropic
object. The implementation of the imaging functionals is simple and avoids the
need to solve an ill-posed problem. The resolution analysis of the imaging
functionals is conducted using the Green representation formula. Furthermore,
we establish stability estimates for these imaging functionals when noise is
present in the data. To illustrate the effectiveness of the methods, we present
numerical examples showcasing their performance.
