Abstract :
In this paper, a novel realization of the FFT-based methods for the EFIE with high accuracy is established by fitting the Green´s function onto the nodes of a uniform Cartesian grid. Like the IE-FFT, the focus of the proposed method is the Green function, but the accuracy of new method is significantly higher than that of the IE-FFT. Some numerical examples are provided to demonstrate the accuracy and efficiency of the proposed method.
