Bistatic Integrated Sensing and Communications with Flexible Intelligent Metasurfaces
Iván Alexander Morales Sandoval, Thushar Venkataramanaiah, Kuranage Roche Rayan Ranasinghe +3
We propose a novel doubly-dispersive (DD) multiple-input multiple-output (MIMO) channel model incorporating flexible intelligent metasurfaces (FIMs), suitable for integrated sensin…
Characterization of Continuous Electromagnetic Manifolds via Calculus of Variations
Kuranage Roche Rayan Ranasinghe, Miguel Rodrigo Castellanos, Giuseppe Thadeu Freitas de Abreu
The paper introduces a calculus‑of‑variations framework for designing beamformers on continuous electromagnetic manifolds, improving near‑field accuracy and removing hardware‑port…
Group-Connected Riemannian Manifold Optimization for Reciprocal BD-RIS
Marko Fidanovski, Thushar Venkataramanaiah, Eduard Jorswieck +1
Reconfigurable intelligent surfaces (RISs) provide a flexible means of engineering wireless propagation channels through configurable multiport scattering networks. Among their arc…
Fractional Programming and Manifold Optimization for Reciprocal BD-RIS Scattering Matrix Design
Marko Fidanovski, Iván Alexander Morales Sandoval, Kuranage Roche Rayan Ranasinghe +3
We investigate the problem of maximizing the sum-rate performance of a beyond-diagonal reconfigurable intelligent surface (BD-RIS)-aided multi-user (MU)-multiple-input single-outpu…
Reciprocal Beyond Diagonal Reconfigurable Intelligent Surface: Distributed Scattering Matrix Design and MIMO Beamforming via Fractional Programming and Manifold Optimization
Iván Alexander Morales Sandoval, Marko Fidanovski, Hyeon Seok Rou +2
We consider the optimization of beyond diagonal reconfigurable intelligent surface (BD-RIS)-aided multi-user (MU) cell-free (CF)-massive multiple-input multiple-output (mMIMO) syst…
Electromagnetic Signal and Information Theory: A Continuous-Aperture Array Perspective
Zhaolin Wang, Chongjun Ouyang, Kuranage Roche Rayan Ranasinghe +4
Emerging wireless systems are evolving toward larger, denser, higher-frequency, and more reconfigurable apertures, which motivates the study of continuous-aperture arrays (CAPAs).…
