Abstract :
A domain decomposition method based on equivalence principle algorithm is used for analyzing and calculating radiation problems of large-scale arrays. The adaptive cross approximation method is introduced to accelerate computing the translate operator, and the repeatability of the array is removed. Numerical results demonstrate that the time consumption and the memory usage are all reduced.
