About this paper
Marco Di Renzo, Philipp del Hougne
This overview consolidates research on Multiport Network Theory (MNT) as a foundational framework for modeling and optimizing Reconfigurable Intelligent Surfaces (RIS) in wireless communication systems. It demonstrates MNT's capability to provide electromagnetically consistent models that accurately capture mutual coupling and structural scattering, facilitating the design and optimization of smart radio environments.
Key insights
- MNT provides a robust and accurate framework for modeling RIS, offering a favorable tradeoff between electromagnetic accuracy and analytical tractability for communication systems.
- The theory effectively accounts for complex electromagnetic phenomena such as mutual coupling, non-linear end-to-end responses, and structural scattering, which are critical for realistic RIS performance.
- MNT serves as a vital bridge between the physical layer electromagnetics and the system layer communication theory and signal processing for RIS-empowered environments.
