An iterative time‐domain algorithm for reconstructing three‐dimensional (3D) lossy objects using microwave data transmitted and collected by dipole antennas is presented. The electromagnetic and adjoint fields are calculated using the finite‐difference time‐domain (FDTD) method. Numerical examples show the algorithm can rebuild simultaneously from noise‐free and noisy data the permittivity and conductivity of a 3D lossy object settled in a lossless background. © 2005 Wiley Periodicals, Inc.
