Abstract:

To analyze the electromagnetic scattering characteristics on multi-cylinders faster and as accuractely as possible, the iterative induced field ratio(IIFR) algorithm is proposed. The rapidity of the induced field ratio(IFR) theory and precision of the iterative algorithm are mixed together. The iterative induced field ratio of the two-dimensional infinite parallel cylinder array is derived with which the scattering far field of the cylinders array are easily obtained. Furthermore, the relationship between scattering coefficient and iterative times are discussed. The results shows that not only the precision of the proposed algorithm has been improved compared with the traditional induced field ratio method, but also a lot of computer memory and calculating time are saved compared with the method of moments(MoM).

Key words: cylinders array, scattering, iterative induced field ratio(IIFR)
