Abstract: The National Physical Laboratory (NPL) is the UK’s National Measurement Institute (NMI). As such, NPL is tasked with developing, maintaining and disseminating the UK’s primary national standards of measurement. These standards represent the ultimate in measurement accuracy and are used to provide measurement traceability to the international system of units (SI). Standards and associated measurement capability are developed in areas of relevance to science and technology-as new science and technology is established; new measurement standards and measurement capability are needed to underpin and validate the new science and technology.
In recent years, much use has been made of the millimetre- and submillimetre-wave (also known as terahertz) parts of the electromagnetic spectrum. This is for applications in electronics and telecommunications, defence and security, radio astronomy and atmospheric science, and, healthcare and pharmaceuticals. All these applications have driven the need for accurate and reliable measurement capabilities at these frequencies.
This talk will review recent developments being made at NPL to establish such measurement capabilities. Some examples of research and development activities will be given that have recently been undertaken as part of the ‘TEMMT’ European Joint Research Project. (‘TEMMT’ stands for “Traceability for electrical measurements at millimetre-wave and terahertz frequencies for communications and electronics technologies”.) This project involves 19 organizations from around the world and is running from 2019 to 2022.
Biography: Prof. Nick Ridler received the B.Sc. degree from King’s College London, University of London, London, U.K., in 1981. He is currently the Head of Science in the Department of Electromagnetic and Electrochemical Technologies at the UK’s National Physical Laboratory. He is also an Honorary Professor at the University of Liverpool, U.K., a Visiting Professor at the University of Leeds, U.K., a Visiting Professor at the University of Surrey, U.K., and, a Non-Executive Director of LA Techniques Ltd. He is a Fellow of the Institute of Electrical and Electronic Engineers (FIEEE), Fellow of the Institution of Engineering and Technology (FIET) and a Fellow of the Institute of Physics (FInstP). He has almost 40 years’ experience working in industrial, government and academic research establishments. His main area of interest is precision high-frequency electromagnetic measurement (from 1 kHz to 1 THz).
