Efficient Scattering Synthesis for Beyond-Diagonal Non-Local RISs Coupled with Passive Load Networks
Sravan K. R. Vuyyuru, Francisco S. Cuesta, Viktar S. Asadchy +2
Realizing advanced functionalities with high efficiencies via reconfigurable intelligent surfaces (RISs) and reflectarrays requires configurations with strong electromagnetic non-l…
Simultaneous Angle-of-Arrival Sensing and Anomalous Deflection with Aperiodically Loaded Patch Arrays
Mostafa Movahediqomi, Sravan K. R. Vuyyuru, Grigorii Ptitcyn +4
We propose and numerically demonstrate a reconfigurable patch antenna array that enables simultaneous incident wave sensing and anomalous reflection without prior knowledge of the…
Modeling RIS from Electromagnetic Principles to Communication Systems--Part I: Synthesis and Characterization of a Scalable Anomalous Reflector
Sravan K. R. Vuyyuru, Le Hao, Markus Rupp +2
This work aims to build connections between the electromagnetic and communication aspects of Reconfigurable Intelligent Surfaces (RIS) by proposing a methodology to combine outputs…
Efficient Synthesis of Passively Loaded Finite Arrays for Tunable Anomalous Reflection
Sravan K. R. Vuyyuru, Risto Valkonen, Sergei A. Tretyakov +1
A design methodology for planar loaded antenna arrays is proposed to synthesize a perfect anomalous reflection into an arbitrary direction by optimizing the scattering characterist…
