A new reconstruction algorithm as applied to electromagnetic imaging is proposed. It is aimed at reconstructing constitutive parameter distributions of infinitely long dielectric cylinders with arbitrary cross section, from the scattered fields they produce. Computer simulations show that the implementation of the pseudoinverse transformation in this algorithm yields excellent results for thin cylinders irradiated by transverse magnetic (TM) waves, even in the presence of realistic uncertainties in the scattered field measurements.
