    Minimum Data Spherical Spiral NF/FF Transformations for Offset-Mounted Elongated AUTs: An Experimental Validation by Francesco D’Agostino, Flaminio Ferrara, Claudio Gennarelli, Rocco Guerriero, Massimo Migliozzi, Luigi Pascarella, Giovanni Riccio

    Published 2025-06-01
    “…In order to perform the standard NF/far-field transformation (NF/FFT) technique, a non-centered AUT would generally require the collection of a significantly increased amount of voltage data if compared to the onset scenario. This issue is addressed here by using the non-redundant (NR) sampling representations of electromagnetic (EM) fields. …”
