Secure Near-Field ISAC with Pinching-Antenna Systems: Exploiting Constructive-Destructive Interference
Dimitrios Bozanis, Vasilis K. Papanikolaou, Sotiris A. Tegos +3
This paper investigates secure near-field integrated sensing and communication (ISAC) with pinching-antenna systems (PASS), where a base station serves legitimate users while local…
Secure ISAC with Sensing Privacy under Eavesdropper Uncertainty
Pigi P. Papanikolaou, Dimitrios Bozanis, Sotiris A. Tegos +2
This paper investigates the joint protection of confidential data and legitimate-user directional information in integrated sensing and communication (ISAC) networks. We consider a…
Jacobi Elliptic Chirps for Sub-Nyquist Multi-Target Ranging
Dimitrios Bozanis, Thrassos K. Oikonomou, Sotiris A. Tegos +2
Sub-Nyquist sampling is an attractive way to reduce the hardware cost of wideband pulse-compression radar, but it introduces coherent alias-induced replicas in the matched-filter r…
Elliptic Range-Doppler Mapping for OFDM-ISAC under IQ Imbalance
Thrassos K. Oikonomou, Dimitrios Bozanis, Sotiris A. Tegos +2
Receiver in-phase/quadrature imbalance (IQI) couples each OFDM subcarrier with its mirror counterpart, creating ghost targets and degrading range-Doppler recovery in orthogonal fre…
Non-Uniform Codebook Design for Optical IRS-Assisted VLC Systems
Rashid Iqbal, Dimitrios Bozanis, Dimitrios Tyrovolas +4
Optical intelligent reflecting surfaces (OIRS) can improve the coverage of indoor visible light communication (VLC) systems, however, practical deployment requires a finite offline…
Enabling mmWave Communications with VCSEL-Based Light-Emitting Reconfigurable Intelligent Surfaces
Rashid Iqbal, Dimitrios Bozanis, Dimitrios Tyrovolas +4
This paper proposes a light-emitting reconfigurable intelligent surface (LeRIS) architecture that integrates vertical cavity surface-emitting lasers (VCSELs) to jointly support use…
