The Fourier iterative algorithm (FIA) is a well-known planar phase retrieval method. The algorithm uses conventional amplitude measurements on two surfaces placed in different distances from the measured antenna. In this paper FIA will be applied in cylindrical geometry. In this case near-field transformations use high order Hankel functions which are known to become singular in case of measurements close to AUT. In this paper we will analyze properties of Hankel function used for forward anddoaj:3cff7065002044dea94ac737f52a206c fatcat:bo45xfrqrnhr3mbyoct3kwgrsm
