The unified theory of near-field-far-field transformation techniques with spiral scannings for quasi-spherical antennas is extended in this paper to the case of nonspherical ones, i.e., antennas with two dimensions very different from the third one. To this end, such a kind of antennas is ...
Single-Cut Phaseless Near-Field to Far-Field Transformation This paper introduces a fast single-cut near-field to far-field transformation method using amplitude-only data. By measuring the antenna near-field amplit... FR Varela,BG Iragüen,MS Castaer - 《European Conference on Antennas & Propa...
multilevel plane wave based near-field far-field transformation utilising combined near- and far-field translationsThe radiation of large antennas and those operating at low frequencies can be determined efficiently by near-field measurement techniques and a subsequent near-field far-field transformation....

An efficient near-field-far-field transformation technique with spherical spiral scanning, which uses a minimum number of data, is proposed. A nonredundant sampling representation of the electromagnetic field on the spiral and a fast, accurate and stable interpolation algorithm are developed to this ...
