An iterative spherical near-field to far-field emissions and source reconstruction using the equivalent current approach

The near-field to far-field transformation problem of radiating emissions from an equipment under test (EUT) is addressed in this paper from the point of view of equivalent radiating sources. The EUT must be mounted on a two axis positioner so that a hemispherical scanning can be performed. An iterative efficient matrix method, based on equivalent current reconstruction and radial field retrieval, is proposed. Direct planar diagnosis over the EUT is also addressed
