Wireless communication is vulnerable to malicious jamming and eavesdropping attacks due to the broadcast nature of wireless channels. An extremely-large-scale reconfigurable intelligent surface (XLRIS) demonstrates its abilities to enhance the physical layer security (PLS) and compensate for the sev...
