Secure Simultaneous Wireless Information and Power Transfer in Multiuser STAR-RIS Aided MISO Rate Splitting Downlink
The authors propose a secure STAR-RIS-aided SWIPT solution for a MISO downlink network employing rate-splitting multiple access (RSMA), where the transmitter concurrently communicates with information receivers (IRs) and sends energy to untrusted energy receivers (UERs) in the transmission and reflection spaces of the STAR-RIS.
