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…

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…
