Tian Loh

Dr Tian Hong Loh is leading work at NPL on applied and computational electromagnetic metrology research in support of the electronics and communications industry. His current research interests include metamaterials, small and smart antennas, computational electromagnetics, electromagnetic compatibility, body-centric and in-vehicle wireless sensor network communications, photonic crystal, and signal propagation, multi-hop, data transfer and data clustering in wireless communications, and wireless sensor networks.


Tian Hong received a BEng degree (first class) from Nottingham Trent University in 1999, and a PhD degree from the University of Warwick in 2005, both in electrical and electronic engineering. His PhD work focused on computational electromagnetics for microwave devices incorporating periodic structures using various finite element methods. The research work was sponsored under an EPSRC/MOD grant and by the University of Warwick. During the study, he was also involved in a research contract on wireless communication signal guidance around building, which was sponsored by the Radiocommunications Agency, UK (now known as Ofcom). From 1999 to 2000, he was an Electrical Engineer with Sharp-Roxy Inc, Batu Pahat, Malaysia.

Tian Hong joined the National Physical Laboratory in 2005 as a Higher Research Scientist, and since 2009 has been a Senior Research Scientist. He is involved in fundamental research and develops measurement technologies in support of the electronics and communications industry. He has also been involved in bidding for and delivering several European Space Agency (ESA), UK National Measurement Office (NMO), UK Technology Strategy Board (TSB), NPL Strategic Research (SR), and NPL-EPSRC Industrial CASE projects.

Tian Hong has a wide range of skills and technical expertise in various areas in microwave antennas and electromagnetic measurements and analysis. He holds two patents and has authored or co-authored over 50 refereed publications and conference contributions on applied and computational electromagnetics. He has also acted on the technical programme committee for several international conferences and as technical reviewer for several international journals and new book proposals on these subjects.

Tian Hong is a member of the Institute of Electrical and Electronics Engineers (IEEE) and the Institution of Engineering and Technology (IET).
