The integration of sensing and communication is one of the key feature for 6G networks, but its deployment raises serious concerns over privacy, security, and robust target detection under hostile conditions. In downlink massive multiple-input multiple-output systems, this letter examines the design of a secure multi-t...

Wideband terahertz (THz) communication systems assisted by active reconfigurable intelligent surfaces (RIS) are susceptible to frequency dependent beam squint, which degrades the array gain at band edge subcarriers and reduces the achievable rate. In active RIS architectures, mitigating this effect requires the inserti...
