   Abstract:
   An accurate conjugate gradient fast Fourier transform (CG-FFT) for solving electromagnetic scattering problems is developed by improving the accuracy of estimating the spectrum of the Green's function. Comparing to the traditional CG-FFT algorithm, this new approach reduces the relative error by a factor of 5 to 20 for one-dimensional electromagnetic scattering models while maintaining the computational cost in terms of CPU time and memory requirement. © 2005 IEEE.
