Secrecy outage of SWIPT in the presence of cooperating eavesdroppers [PDF]
AEU - International Journal of Electronics and Communications, 2017 This work investigates the secrecy performance of a simultaneous wireless information and power transfer system that operates in the presence of cooperating eavesdroppers. The multi-antenna access point’s transmission is used for information-decoding by a multi-antenna node and for energy-harvesting (EH) by multiple single-antenna nodes.

Robust Spectral and Energy Efficiency Tradeoff for RIS‐Aided Multi‐User Communication
IET Communications, Volume 20, Issue 1, January/December 2026.In this work, an RIS‐aided multi‐user network with imperfect CSI is investigated. Correspondingly, we focus on balancing SE and EE through the collaborative design of the base station (BS)'s precoding matrix and the RIS's phase shifts, which consider the transmit power budget and the channel uncertainties constraints.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper develops a focal‐curvature‐aware near‐field ISAC framework for a distributed parallel STAR‐RIS‐assisted system employing a cylindrical‐array base station. Exact spherical‐wave propagation and reciprocal wideband sensing are used to derive an energy–curvature relationship linking focal energy, focal‐coherence curvature, EFIM, and PEB ...
