Near-field (NF) measurement techniques and the associated transformations from near-field to far-field (NF-FF) are increasingly valued for accurately assessing the radiation characteristics of antennas that are too electrically large for direct far-field measurements in controlled, reflection-free environments like anechoic chambers.
This book offers a thorough exploration of classical NF-FF transformation methods and details the significant performance improvements achieved by applying non-redundant sampling representations to antenna radiated electromagnetic fields.
Non-Redundant Near-Field to Far-Field Transformation Techniques is intended for students studying antenna NF measurements, as well as engineers and physicists in the field. The book has two main goals: first, to provide complete analytical details on deriving classical NF-FF transformation techniques, both with and without probe compensation—information that is rarely found elsewhere; and second, to comprehensively describe effective representations of EM fields radiated over arbitrary rotational surfaces, using a non-redundant (minimum) number of samples collected on these surfaces or along spirals that wrap around them.
