✦ Synopsis

A new iterati¨e algorithm for the reconstruction of twodimensional lossless objects is de¨eloped using time-domain scattering data. All of the calculations in both the forward and in¨ersion algorithms are carried out efficiently in the time domain using the finite-difference ( ) time-domain FDTD method. Computer simulations are presented to illustrate the usefulness of the present method.
