RIShield: Enabling Electromagnetic Blackout in Radiation-Sensitive Environments
arxiv(2023)
摘要
Reconfigurable Intelligent Surfaces (RIS) have emerged as a disruptive
technology with the potential to revolutionize wireless communication systems.
In this paper, we present RIShield, a novel application of RIS technology
specifically designed for radiation-sensitive environments. The aim of RIShield
is to enable electromagnetic blackouts, preventing radiation leakage from
target areas. We propose a comprehensive framework for RIShield deployment,
considering the unique challenges and requirements of radiation-sensitive
environments. By strategically positioning RIS panels, we create an intelligent
shielding mechanism that selectively absorbs and reflects electromagnetic
waves, effectively blocking radiation transmission. To achieve optimal
performance, we model the corresponding channel and design a dynamic control
that adjusts the RIS configuration based on real-time radiation monitoring. By
leveraging the principles of reconfiguration and intelligent control, RIShield
ensures adaptive and efficient protection while minimizing signal degradation.
Through full-wave and ray-tracing simulations, we demonstrate the effectiveness
of RIShield in achieving significant electromagnetic attenuation. Our results
highlight the potential of RIS technology to address critical concerns in
radiation-sensitive environments, paving the way for safer and more secure
operations in industries such as healthcare, nuclear facilities, and defense.
