报告1：“Research to Realization” - From molecular level interaction to real-time monitoring electronic systems

时间：10:00-10:40

报告人：Roy Vellaisamy, Professor, University of Glasgow

报告摘要：

Growing industrialization and urbanization has put human beings and other living organisms at risk against new threats due to the contamination of food, water and air. These Contaminants endanger all the living organisms in this world, especially for human beings’ genetic disorders. The WHO statistics show that more than 422 million people worldwide are suffering from contamination related illness. The growing prevalence of such disorders has been linked to exposure to chemicals in plastic, food and water. Although regulatory steps have been taken to minimize risk, cases of overexposure still occur. In this talk, I will present our real-time monitoring system for a rapid pre-screening test that could curtail cases of contamination. Over the years, we have developed an electronic sensor platform based on molecular level interaction between the target and analyte to detect various toxins. The advantage of our sensor platform is that it can be used for on-site detection; it is easy to operate and provides results on real-time basis. In addition, we have extended our sensor platform system for healthcare applications such as detection of cancer biomarkers and monitor pulse waveform in real-time. In this talk, I will present our recent accomplishments on intelligent sensing, neuromorphic devices, and next generation communication materials.

报告2：Be Water My Friend - It may change the future mobile communications

时间：10:40-11:20

报告人：Kin-Fai (Kenneth) Tong (湯建輝), Professor, IEEE Fellow, University College London

报告摘要：

Many people know the famous quote of Bruce Lee: “Empty your mind, be formless, like water”. Such concept has been proven very effective in Martial Art, but can we apply similar concept to our scientific research?

With research efforts gearing up to build the sixth-generation (6G) mobile communications, it is only logical to seek new mobile technologies that can provide the next generational leap for much better performance under harsher environments. To this end, one interesting concept is fluid antenna system (FAS) which utilizes flexible antenna architectures such as liquid-based antennas, reconfigurable RF pixel-based antennas, stepper motor-based antennas, and etc., to enable reconfigurability of antenna’s position (i.e., port). In so doing, tremendous space diversity can be obtained in a novel way. The possibility of accessing seemingly a continuous fading envelope in the spatial domain also means that multiple access can be realized in a simple manner without complex optimization and processing. This is the first of a three-part letter that reviews the basic principles of FAS. Our scope focuses on the physical-layer performance metrics and we discuss the evolution of the channel models being adopted for FAS and summarize the key results highlighting its potential.

In this talk, we will share our experience with you how fluid antenna may replace its solid counterpart and be used in mobile communications. How fluid’s formless feature can solve the problems in modern wireless communications. Although you may not see any board breaking demonstration, hopefully it could inspire you to some new ground-breaking ideas.

报告3：Functional-Material Integrated High-Frequency Devices for Millimeter-wave and Terahertz Applications

时间：11:20-12:00

报告人：Hang Wong (黃衡) (Deputy Director, State Key Laboratory of Terahertz and Millimeter Waves, City University of Hong Kong)

报告摘要：

Technology market forecasts high-frequency products will boost up rapidly in the coming decades not only the popular microwave electronics but also that of unreleased millimeter-wave and terahertz inventions. Scientists put hard efforts to demonstrate both feasibility and capability of the new allocated frequency spectrum by ITU from 110 to 450 GHz that can be commercialization through the introduction of emerging applications of wireless systems such as 6G communications, terahertz imaging, millimeter-wave detection and sensing, low-orbit space communications, intelligent ultra-fast wireless, green energy network, etc. In this talk, the speaker is going to introduce recent high-frequency electronic developments by other world-leading antenna research groups and share state-of-the-art antenna technologies invented at the State Key Laboratory of Terahertz and Millimeter Waves, City University of Hong Kong. Breaking through the bottleneck of PIN diode at high-frequency devices, the speaker will demonstrate some examples of using functional materials to design millimeter-wave and terahertz reconfigurable, tunable, and switchable devices including antennas, metasurfaces, polarizers, modulators, and filters.
