Simulation of the Electromagnetic Far-Field Scattered by an Object Based on Measurements of the Near-Field on a Scanning Segment in the Scalar Two-Dimensional Case

Near-field measurement for scanning over a plane surface in two-dimensional scalar case is simulated for the diffraction on a dialectical infinite circular cylinder. The development of the method [1]-[4], based on the expansion of Slepyan functions to a scalar two-dimensional case when scanning over a flat surface, is proposed. The method is numerically tested in the case of diffraction on an infinite dielectric circular cylinder.
