Abstract :
We have solved the transient scattering problem by a CGFFT iterative method, both in space and time. We do not need the doubling of the time interval in the conjugate gradient method described in (Tijhuis 1991). In each iteration the computational complexity is roughly of the order of MNPlog(MNP).
