摘要

我们用CGFFT迭代法在空间和时间上分别求解了瞬态散射问题。在(Tijhuis 1991)中描述的共轭梯度方法中，我们不需要将时间间隔加倍。每次迭代的计算复杂度大致为MNP (MNP)的数量级。

A conjugate gradient FFT method for transient scattering by dielectric cylinders

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).
