In this paper, the tangential equivalence principle algorithm (T-EPA) combined with characteristic basis functions (CBFs) is presented to analyze the electromagnetic scattering of large-scale antenna arrays. The T-EPA is a kind of domain decomposition scheme for the electromagnetic scattering and radiation problems based on integral equation (IE). CBFs are macrobasis functions which are constructed...
The 2-level adaptive integral method is represented in this paper. Two level grids and two level boxes are built for calculating relatively nearer interaction and relatively farer interaction. This algorithm can be used to calculate larger object than the AIM. The last numerical result suggests that the proposed method is efficient and accurate.
