Speech Title: Electromagnetic Selective Surfaces: Concept and Design

Abstract: In this talk, we intend to provide a brief overview of electromagnetic selective surfaces/structures (EMSS). According to the properties of an incident electromagnetic wave, EMSS can be divided into four categories: frequency-selective structure (FSS), polarization-selective surface (PSS), angle-selective surface (ASS), and energy-selective surface (ESS). Recent developments and advances in the design of EMSS will also be briefly introduced. Finally, future opportunities in the areas of the design and analysis of EMSS will be suggested.

Speech Title: Beyond 5G towards a Super-connected World

Abstract: Connected smart objects, platforms and environments have been identified as the next big technology development, enabling significant society changes and economic growth. The entire physical world will be connected to the Internet, referred to as Internet of Things (IoT). The intelligent IoT network for automatic interaction and processing between objects and environments will become an inherent part of areas such as electricity, transportation, industrial control, utilities management, healthcare, water resources management and mining. Wireless networks are one of the key enabling technologies of the IoT. They are likely to be universally used for last mile connectivity due to their flexibility, scalability and cost effectiveness. The attributes and traffic models of IoT networks are essentially different from those of conventional communication systems, which are designed to transmit voice, data and multimedia. IoT access networks face many unique challenges that cannot be addressed by existing network protocols; these include support for a truly massive number of devices, the transmission of huge volumes of data burst in large-scale networks over limited bandwidth, and the ability to accommodate diverse traffic patterns and quality of service (QoS) requirements. Some IoT applications have much stringent latency and reliability requirements which cannot be accommodated by existing wireless networks. Addressing these challenges requires the development of new wireless access technologies, underlying network protocols, signal processing techniques and security protocols. In this talk, I will present the IoT network development, architecture, key challenges, requirements, potential solutions and recent research progress in this area, particularly in 5G and beyond 5G.

Speech Title: Positron Emission Particle Tracking (PEPT) — A Kinematic Imaging Technique for Dynamic Particles in Opaque Flows

Abstract: Positron Emission Particle Tracking (PEPT) is a non-invasive, non-destructive nuclear imaging technique developed for complex multiphase flow systems. It tracks individual tracer particles with millisecond-millimeter spatiotemporal resolution, yielding dynamic parameters such as velocity and turbulence fields. Its physical basis lies in the 511 keV back-to-back collinear gamma-ray photon pairs generated through positron annihilation. These high-energy photons combine strong penetrability with charge neutrality, allowing them to traverse dense opaque media like metals and concrete without being affected by electromagnetic fields. It gives PEPT a unique and irreplaceable advantage in investigating opaque flow fields. PEPT technique relies on three core components: tracer particle preparation, positron detection systems, and localization algorithms. In terms of particle preparation, reliable fabrication of tracers as small as approximately 50 μm has been achieved via either direct activation or indirect labelling. Positron detection hardwares have progressed from early BGO-based cameras to the Super-PEPT system, and are currently moving toward low-cost, digitalized solutions. Regarding localization algorithms, besides the classical Birmingham method, recently developed approaches such as PEPT-ML and PEPT-EM have substantially improved the capability for simultaneous tracking of multiple particles. To date, PEPT has been widely employed in typical processes including stirred tank reactors, pneumatic conveying, fluidized beds, and rotating drums, and provides high-precision experimental validation benchmarks for multiphase models like CFD. Moreover, its application scope is expanding from traditional engineering fields into the life sciences, showing promising potential in frontier areas such as in vivo hemodynamic assessment, microfluidic systems, and drug delivery.
