Abstract
An improved iterative method based on refining the equivalent current density at each iteration step is presented for the electromagnetic imaging of lossless or lossy dielectric objects. Numerical results for two-dimensional structures show that the proposed method yields a faster convergence rate than the original ones, where such a refinement is not implemented. A better image resolution is achieved with less computation time
