Abstract :
The Far Field Approximation (FAA) is an approximate decomposition phase algorithm that is developed based on the distinction between near-field and far-field interactions in the spatial domain. The algorithm is found to have a computational complexity of O(N1.5 ) if the interactive solver method is used. For discussing the accuracy of FFA, a typical example, the bistatic RCS of TE-excited conducting circular and rectangular cylinders are calculated numerically in this paper
