On the Use of Electromagnetic Inversion for Near-Field Antenna Measurements: A Review

This paper focuses on some features and developments pertaining to the source reconstruction method (SRM), an electromagnetic inverse source technique, for near-field antenna measurements. In particular, we describe the usefulness of the absence of restrictions on the measurement and reconstruction domains in the inverse source framework, which can lead to the development novel systems such as a pendulum-based measurement system. The application of the inverse source framework to phaseless (amplitude-only) near-field measurements using a multiplicative regularization scheme is reviewed, as well as the use of pre-scaled measurement data to improve the accuracy of the calculated far-field pattern.
