Mutual-Coupling-Aware Movable and Fluid Antennas on Holographic Surfaces: A Wavenumber-Domain Circuit-Field Unification
Giovanni Iacovelli, Chandan Kumar Sheemar, Symeon Chatzinotas
Movable and fluid antenna systems turn antenna position into a design variable. At sub-wavelength spacings, however, their behavior is governed by mutual coupling, modeled today by…
Performance Analysis of RSMA-Enabled Bistatic ISAC in LEO Networks with Holographic Apertures and Fluid-Antenna Users
Wali Ullah Khan, Chandan Kumar Sheemar, Muhammad Adil +1
This paper develops an ergodic performance framework for rate-splitting multiple access (RSMA)-enabled bistatic integrated sensing and communication (ISAC) in a low-Earth-orbit (LE…
Terahertz Inter-Satellite Links: Motivation, Challenges and Opportunities
Chandan Kumar Sheemar, Wali Ullah Khan, Giovanni Iacovelli +5
Inter-satellite links (ISLs) are essential to the evolution of next-generation satellite constellations, providing the foundation for low-latency, resilient, and globally scalable…
Energy Efficient Multi-User Beamforming and 3D Position Optimization for SIM-Assisted UAVs
Chandan Kumar Sheemar, Giovanni Iacovelli, Sourabh Solanki +3
This paper studies energy-efficient downlink multi-user transmissions with unmanned aerial vehicle (UAV) communication systems equipped with stacked intelligent metasurfaces (SIM),…
Extremely Large Beyond-Diagonal RIS: Low-Rank Modal Optimization for Near-Field Communications
Giovanni Iacovelli, Chandan Kumar Sheemar, Eva Lagunas +1
Beyond-diagonal reconfigurable intelligent surfaces (BD-RIS) achieve their best performance when fully connected, at the price of an optimization and hardware burden that grows qua…
Wavenumber-Domain Virtual Arrays for Holographic Near-Field Localization
Giovanni Iacovelli, Chandan Kumar Sheemar, Symeon Chatzinotas
Monostatic localization of multiple point targets is studied for a holographic aperture operated through wavenumber-domain modes. A specular-point condition delimits the validity o…
