Abstract :
In this paper, we present a mixed time-frequency optimized AFP scheme that can solve a 1D/2D/3D TFSF problem. For bandlimited source, the proposed technique can easily secure an incident field leakage error reaching a machine noise limit with very few sampling points. The complication of the frequency dependent polarization will be resolved by an FDTD anisotropic projection operation. The memory issue is avoided by making the incident wave propagate at rational angles because these angles effectively reduce a Huygen´s surface to a Huygen´s line.
