PhD Qualifying Examination


Title: "Reconfigurable Intelligent Surface assisted Wireless Sensing: A 
Survey"

by

Mr. Chenggao LI


Abstract:

Recent years have witnessed a rapid development of wireless sensing 
applications due to their non-intrusiveness, low-cost and pervasiveness. 
Communication technologies operating in different frequency bands, such as 
Wi-Fi, mmWave and RFID have been proposed to achieve many applications. 
However, although the sensing capabilities of these communication 
technologies have been almost developed, there are still some open issues 
that prevent wireless sensing applications from deploying in real life. 
Reconfigurable Intelligent Surface (RIS), as known as a promising 
technique in 6G communication, becomes popular as its strong ability to 
customize the wireless environment. Many researchers realize its potential 
capabilities can be used to improve the performance of wireless sensing. 
In this survey, we first introduce the principle and existing testbeds of 
RIS. Then we explain the preliminaries of wireless sensing and review the 
related research categorized in terms of their applications. Next, we 
introduce RIS assisted smart applications from two perspectives of 
communication and sensing scenarios. What’s more, we also introduce our 
RIS prototype and ongoing research about RIS-aided multiuser indoor 
localization as our first attempt on RIS assisted wireless sensing. 
Finally, we point out future potential directions and summarize our 
survey.
