Simultaneous Secure Communications and Sensing Privacy with Full Duplex MIMO Radios
Ioannis Gavras, George C. Alexandropoulos
This paper proposes a Full Duplex (FD) framework for safeguarding Integrated Sensing and Communications (ISAC) against a passive multi-antenna Eavesdropper (Eve). The adversary is…
Wideband Sensing with Dynamic Metasurface Antennas under Realistic Phase Response Modeling
Ioannis Gavras, George C. Alexandropoulos
This paper investigates the impact of practical features of the emerging antenna array technology of Dynamic Metasurface Antennas (DMAs) when used for wideband sensing. By adopting…
RIS-Enabled Spoofing Against Adversary Sensing: CRB-Maximizing Design and Decoying Analysis
Ioannis Gavras, Giuseppe Thadeu Freitas de Abreu, George C. Alexandropoulos
This paper studies the capability of a Reconfigurable Intelligent Surface (RIS), when transparently covering a User Equipment (UE), to deceive an adversary monostatic radar system.…
