A reconstruction algorithm for microwave imaging based on the Modifed Pertur-bation Method (MPM) is proposed. Both the object conductivity and permittivity (z.epsi;) are reconstructed. The original Perturbation method developed for static problems was modifed in order to apply in time harmonic problem in higher frequency. The Jacobian matrix is now calculated in closed form employing an adjoint network theorem in conjunction with the reci- procity theorem of electromagnetics. A number of successful reconstructions were carried out for different complex permittivity profles, but all of them based on a computer phantom approach.
