Abstract
In this paper, the question of sampling the near field of conformal sources is addressed for some source and observation geometries. At first, the minimum number of sampling points required to discretize the near field without loss of information is computed by an analytical evaluation of the number of degrees of freedom (NDF). Then, the location of the field samples is found and an interpolation formula is provided.The analysis is performed for a 2D scalar geometry consisting of an elliptical/parabolic arc source whose radiated field is observed over a circumference arc in near zone.
