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…
Analysis of Scalable Anomalous Reflectors through Ray Tracing and Measurements
Le Hao, Sravan K. R. Vuyyuru, Sergei A. Tretyakov +2
In this study, we elaborate on the concept of scalable anomalous reflector (AR) to analyze the angular response, frequency response, and spatial scalability of a designed AR across…
Modeling RIS from Electromagnetic Principles to Communication Systems--Part II: System-Level Simulation, Ray Tracing, and Measurement
Le Hao, Sravan K. R. Vuyyuru, Sergei A. Tretyakov +3
In this paper, we systematically study the electromagnetic (EM) and communication aspects of an RIS through EM simulations, system-level and ray-tracing simulations, and finally me…
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…
