RASRE: Reflectarray and Applications in Smart Radio Environment

Tue, 10 Dec 2024 00:00:00 -1000

Executive Summary

Reflectarray present a paradigm shift in wireless communication and sensing in mmWave and sub-THz region by offering unprecedented control over the propagation environment. Traditional wireless systems are largely at the mercy of the channel, which can be severely impaired by obstacles, fading, and interference. Reflectarray, however, introduce a new degree of freedom by enabling programmable manipulation of the wireless channel. Through precise control of the reflection and refraction properties of an array of elements, reflectarray can be used to mitigate path loss, combat fading, null interference, and shape radiation patterns, which can be used to enhancing spectral efficiency, energy efficiency, and expanding coverage. This project aims to investigate the fundamental principles of reflectarray operation, develop novel reflectarray architectures and control algorithms, and explore their applications in a wide range of wireless communication, sensing, energy transfer, and security scenarios.

MONET: Millimeter-wave Communication and Sensing Integration

Mon, 09 Dec 2024 00:00:00 -1000

Executive Summary

Imagine a future where our wireless devices do more than just talk to each other. They can also “see” and “feel” their surroundings, gathering valuable information about the environment. This is the promise of Integrated Sensing and Communication (ISAC), and millimeter-wave (mmWave) frequencies are the key to unlocking its full potential. Leveraging the abundant bandwidth at mmWave band (30GHz ~ 300GHz), which are currently being explored for future generation of wireless communication systems (cellular and Wi-Fi), radar-like precise and multi-target detection can be implemented, with applications in drone detection, physiological monitoring, smart RAN etc. This VIP project, therefore, see to develop new techniques and technologies to make ISAC a reality at mmWave frequencies.
