NF‐FF transformation with cylindrical scanning from a minimum number of data

In this paper, an efficient sampling representation for reconstructing the voltage measured by a probe over a cylinder in the antenna NF region from a minimum number of data is proposed, and properly exploited to develop two probe compensated NF–FF transformation techniques. They are based on the theoretical results relevant to the nonredundant representation of electro‐magnetic fields. Numerical examples assess the accuracy and stability of the techniques.
