Reconfigurable Intelligent Surface (RIS)

Overview

This tool models the use of Reconfigurable Intelligent Surfaces (RIS) to mitigate turbulence, scattering, and signal degradation in optical wireless communication environments. It simulates passive or hybrid (active/passive) RIS deployments that dynamically adjust reflection phase profiles to steer beams, enhance signal power, and reduce fading in challenging atmospheric or underwater channels. The tool provides insights into how RIS can be leveraged for link reliability, beamforming, and energy efficiency.
