TL;DR: An overview of SWIPT systems with a particular focus on the hardware realization of rectenna circuits and practical techniques that achieveSWIPT in the domains of time, power, antennas, and space is provided.
Journal ArticleDOI
Practical Non-Linear Energy Harvesting Model and Resource Allocation for SWIPT Systems
TL;DR: Numerical results unveil a substantial performance gain that can be achieved if the resource allocation design is based on the proposed non-linear energy harvesting model instead of the traditional linear model.
Journal ArticleDOI
Fundamentals of Wireless Information and Power Transfer: From RF Energy Harvester Models to Signal and System Designs
TL;DR: This paper highlights three different energy harvester models, namely, one linear model and two nonlinear models, and shows how WIPT designs differ for each of them in single-user and multi-user deployments, and identifies the fundamental tradeoff between conveying information and power wirelessly.
Journal ArticleDOI
Robust and Secure Wireless Communications via Intelligent Reflecting Surfaces
TL;DR: In this article, the authors investigated the joint design of the beamformers and AN covariance matrix at the AP and the phase shifters at the RISs for maximization of the system sum-rate while limiting the maximum information leakage to the potential eavesdroppers.
