Near-Field Communication with Movable Antennas: Electrostatic Equilibrium

This paper addresses the challenge of antenna placement in near-field massive MIMO systems to improve spectral efficiency. It proposes a novel approach based on electrostatic equilibrium, offering a computationally efficient solution for optimal antenna positioning. The work's significance lies in its innovative reformulation of the antenna placement problem and the development of an ODE-based framework for efficient optimization. The asymptotic analysis and closed-form solution further enhance the practicality and applicability of the proposed scheme.
