Modeling and Architecture Design of Reconfigurable Intelligent Surfaces Using Scattering Parameter Network Analysis
Shanpu Shen, Bruno Clerckx, Ross Murch
Reconfigurable intelligent surfaces (RISs) are an emerging technology for future wireless communication. The vast majority of recent research on RIS has focused on system level opt…
Wireless Power Transfer with Distributed Antennas: System Design, Prototype, and Experiments
Shanpu Shen, Junghoon Kim, Chaoyun Song +1
In this paper, we design and experiment a far-field wireless power transfer (WPT) architecture based on distributed antennas, so-called WPT DAS, that dynamically selects transmit a…
Beamforming Optimization for MIMO Wireless Power Transfer with Nonlinear Energy Harvesting: RF Combining versus DC Combining
Shanpu Shen, Bruno Clerckx
In this paper, we study the multiple-input and multiple-output (MIMO) wireless power transfer (WPT) system so as to enhance the output DC power of the rectennas. To that end, we re…
Joint Waveform and Beamforming Optimization for MIMO Wireless Power Transfer
Shanpu Shen, Bruno Clerckx
In this paper, we study a multi-sine multiple-input multiple-output (MIMO) wireless power transfer (WPT) system with the objective to increase the output DC power. We jointly optim…
Enhancing Ambient Backscatter Communication Utilizing Coherent and Non-Coherent Space-Time Codes
Wenjing Liu, Shanpu Shen, Danny H. K. Tsang +1
Ambient backscatter communication (AmBC) leverages the existing ambient radio frequency (RF) environment to implement communication with battery-free devices. The key challenge in…
