Computational Lens for the Near Field
Physical Review Letters, 2004 A method is presented to reconstruct the structure of a scattering object from data acquired with a photon scanning tunneling microscope. The data may be understood to form a Gabor type near-field hologram and are obtained at a distance from the sample where the field is defocused and normally uninterpretable.

Low-Complexity High-Order Propagator Method for Near-Field Source Localization
Sensors, 2018 In this paper, an efficient high-order propagator method is proposed to localize near-field sources. We construct a specific non-Hermitian matrix based on the high-order cumulant of the received signals.

Non-Uniform sampling in near field measurement: Experimental results
, 2021 In this paper, the problem of sampling the field radiated by a planar source observed over a finite planar aperture located in the near-field is addressed. In particular, the paper is devoted to assess the performance of the sampling strategy proposed in
