Near-Field Spot Beamfocusing: A Correlation-Aware Transfer Learning Approach
Mohammad Amir Fallah, Mehdi Monemi, Mehdi Rasti +1
Three-dimensional (3D) spot beamfocusing (SBF), in contrast to conventional angular-domain beamforming, concentrates radiating power within a very small volume in both radial and a…

A Study on Characterization of Near-Field Sub-Regions For Phased-Array Antennas
Mehdi Monemi, Sirous Bahrami, Mehdi Rasti +1
We characterize three near-field sub-regions for phased array antennas by elaborating on the boundaries {\it Fraunhofer}, {\it radial-focal}, and {\it non-radiating} distances. The…

Revisiting the Fraunhofer and Fresnel Boundaries for Phased Array Antennas
Mehdi Monemi, Mehdi Rasti, Matti Latva-aho
This paper presents the characterization of near-field propagation regions for phased array antennas, with a particular focus on the propagation boundaries defined by Fraunhofer an…
