Abstract : T o analyze the electromagnetic scattering characteristics on multi cylinders faster and as
accuractely as possible , the iterative induced field ratio ( IIFR) algorithm is proposed . T he rapidity of the
induced field ratio ( IFR) theory and precision of the iterative algorithm are mix ed together . T he iterative
induced field ratio of the tw o dimensional infinite parallel cylinder array is derived w ith w hich the scattering
far field of the cylinders array are easily obtained . Furthermore , the relationship betw een scattering
coefficient and iterative times are discussed . T he results show s that not only the precision of the proposed
algorithm has been improved compared w ith the traditional induced field ratio method , but also a lot of
computer memory and calculating time are saved compared w ith the method of moments( M oM ) .
