Computational electromagnetic model of a cylindrical near-field antenna test system: Examination of common measurement errors and their compensation

This paper presents the results of a new computational electromagnetic simulation of a cylindrical near-field antenna test system. The new plane-wave spectrum representation based simulation allows many of the commonly encountered components within the range uncertainty budget to be included within the model. These terms are: range reflections, random errors and cylindrical measurement truncation. This paper presents the results of simulations that verify the utility of the cylindrical mathematical absorber reflection suppression (C-MARS) technique for compensation of their effects. Although past verifications have been done using experimental techniques this paper, for the first time, corroborates these findings using purely computational methods.
