报告人简介:Prof Tian Hong Loh is a Principal Research Scientist at the UK National Physical Laboratory (NPL). He leads work at NPL on a wide range of applied and computational electromagnetic metrology research areas to support the telecommunications industry. He has authored and co-authored over hundred refereed publications and hold five patents.
He is currently visiting professor at Surrey University, visiting industrial fellow at Cambridge University, UK representative of Union Radio-Scientifique Internationale (URSI) Commission A (Electromagnetic Metrology), project coordinator of an European Association of National Metrology Institutes (EURAMET) European Metrology Programme for Innovation and Research (EMPIR) project on ‘Metrology for 5G Communications’, member of the Institution of Engineering and Technology (IET) and senior member of the Institute of Electrical and Electronics Engineers (IEEE). He is a guest editor of IET Microwaves, Antennas & Propagation (MAP) special issue on ‘Metrology for 5G Technologies’, an associate editor of IET MAP, IET Communications (COMMS) Journals, associated editor of URSI radio science bulletin (RSB) and was the TPC chair of 2017 IEEE International Workshop on Electromagnetics (iWEM 2017). He has over 20 years of research experience in areas of antennas, electromagnetics, RF/microwave, wireless communications and radio propagation. He also has acted on the session chair and technical programme committee for several international conferences, and as technical reviewer for several international journals and new book proposals on these subjects. His current research interests include 5G communications, multiple-input-multiple-output (MIMO), smart antennas, small antennas, metamaterials, body-centric communications, wireless sensor network (WSN), electromagnetic compatibility (EMC), and computational electromagnetics.
报告内容:High bandwidth mobile communication is an essential tool for wealth creation. The rapid growth of the wireless communications market coupled with the desired to make optimum use of the available spectrum is driving research into development of affordable novel antenna and wireless communication technologies being investigated. The advancement in these areas enable new applications been constantly developed where complex performance are often required. As a raft of emerging wireless technologies increasingly emerge in the arena of modern devices, antenna and system design, the standards bodies, industries, and research communities are facing the challenge on verifying products that meet desired performance parameters. It is important to have a good understanding of the antenna and wireless communication systems as these ultimately affect the coverage and reliability of the network radio links. It is anticipated that the future generation wireless communications to consider sub-6 GHz, millimetre wave (mm-wave), Tera-Hertz (THz) and even optical spectrum bands to support a significantly increased user density and to meet the promises on energy saving and reliable communications with high bandwidth. Testing at these bands presents new challenges both within the system and in free-space. The National Physical Laboratory (NPL) is the UK’s National Measurement Institute and is a world leading centre of excellence in developing and applying the most accurate measurement standards, science and technology. This talk presents some research highlights and capabilities in electromagnetic and communication technologies carried out at the NPL as well as overview of other international effort for 5G and Beyond. The topics to cover include multiple-input-multiple-output over-the-air (MIMO-OTA), massive MIMO, 5G antenna designs, smart antenna, electrically small antennas, mm-wave hybrid beamforming phased array, software defined radios (SDR), Li-Fi, 3D holographic displays, location-awareness wireless sensor networks, body-worn antennas, metamaterials, etc. Some demonstrable impact examples will also be presented. This talk will cover also an overview of NPL.
