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…
Practical Challenges for Reliable RIS Deployment in Heterogeneous Multi-Operator Multi-Band Networks
Mehdi Monemi, Mehdi Rasti, Arthur S. de Sena +3
Reconfigurable intelligent surfaces (RISs) have been introduced as arrays of nearly passive elements with software-tunable electromagnetic properties to dynamically manipulate the…
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…
Towards Near-Field 3D Spot Beamfocusing: Possibilities, Challenges, and Use-cases
Mehdi Monemi, Mohammad Amir Fallah, Mehdi Rasti +2
Spot beamfocusing (SBF) is the process of focusing the signal power in a small spot-like region in the 3D space, which can be either hard-tuned (HT) using traditional tools like le…
