One-Shot Beam Tracking for Stacked Intelligent Metasurfaces-Assisted LEO Broadcasting
Chandan Kumar Sheemar, Giovanni Iacovelli, Sourabh Solanki +2
This letter develops a physics-informed one-shot beam tracking method for stacked intelligent metasurface (SIM)-enabled low-Earth-orbit (LEO) links with users and an -layer…
Stacked Fluid Metasurfaces: Mutual-Coupling-Aware Modeling and Optimization
Giovanni Iacovelli, Chandan Kumar Sheemar, Symeon Chatzinotas
Stacked intelligent metasurfaces process the transmitted field layer by layer, and fluid antennas make the position of every radiator a design variable. Combined, they pack radiato…
Leveraging Movable-Element STARS for RSMA-SWIPT Under Practical System Imperfections
Muhammad Asif, Asim Ihsan, Irfan Muhammad +3
We study a robust multiuser framework for simultaneous wireless information and power transfer (SWIPT), where rate-splitting multiple access (RSMA) is integrated with a movable-ele…
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…
