A Physically Consistent Assessment of Nearfield Beamfocusing into Occluded Regions
Georg Schwan, Alexander Stutz-Tirri, Christoph Studer
Recent work has explored elaborate beamfocusing techniques for the radiative nearfield, with some studies suggesting that certain beamshapes, such as Airy beams, can enable efficie…
On Near-Far-Field Boundaries in Wireless Systems
Alexander Stutz-Tirri, Ahmad Dkhan, Hadi Sarieddeen +1
Near-field (NF) multi-antenna wireless communication and sensing have attracted growing research interest in recent years. A core question in this area is how to determine whether…
Physically Consistent Evaluation of Commonly Used Near-Field Models
Georg Schwan, Alexander Stutz-Tirri, Christoph Studer
Near-field multi-antenna wireless communication has attracted growing research interest in recent years. Despite this development, most of the current literature on antennas and re…
Joint Beamforming and Matching for Ultra-Dense Massive Antenna Arrays
Carolina Nolasco-Ferencikova, Georg Schwan, Raphael Rolny +2
Massive multiple-input multiple-output (MIMO) offers substantial spectral-efficiency gains, but scaling to very large antenna arrays with conventional all-digital and hybrid beamfo…
Efficient and Physically-Consistent Modeling of Reconfigurable Electromagnetic Structures
Alexander Stutz-Tirri, Georg Schwan, Christoph Studer
Reconfigurable electromagnetic structures (REMSs), such as reconfigurable reflectarrays (RRAs) or reconfigurable intelligent surfaces (RISs), hold significant potential to improve…
