Near-field (NF) measurement techniques and the related NF to far-field (FF) transformations
are gaining interest for their ability to allow an accurate evaluation of the radiation …

The conditioning and accuracy of various inverse surface-source formulations are
investigated. First, the normal systems of equations are discussed. Second, different …

Emerging 5G and Beyond wireless systems are putting the focus on millimeter-wave (mmW)
and sub-THz antenna systems with multiple beams and a large number of elements yielding …

Inverse source solvers determine spatially distributed radiation sources in a way that their
fields reproduce known observations, commonly obtained by measurements. The spatial …

Compressive sensing (CS) has been deployed in a variety of fields including wideband
spectrum sensing, active user detection, and antenna arrays. In massive multiple input …

We describe a method to use numerical simulations concurrently with measurements (near-
field data) to characterize the radiation properties of an antenna (far-field) with a strongly …

In this article, the goal is to design deterministic sampling patterns on the sphere and the
rotation group and, thereby, construct sensing matrices for sparse recovery of band-limited …

Field sampling should be devised to preserve the information required for the knowledge of
the radiation of an antenna. In this paper, we introduce a sampling scheme based on an …

In this article, we address the problem of reducing the number of required samples for
spherical near-field (SNF) antenna measurements by using compressed sensing (CS). A …

The paper addresses the question of efficiently sampling the near field and its intensity over
an arbitrary curved line. It aims at finding the minimum number of measurements and their …
