NPL scientists chair workshop at European Microwave Week

As part of European Microwave Week 2020, Xiaobang Shang, Senior Research Scientist, and Nick Ridler, Fellow, at NPL, have chaired a workshop based on the European Metrology Programme for Innovation and Research (EMPIR) project on millimetre-wave and terahertz measurement techniques.

There is a rapid increase in exploitation of the millimetre-wave and submillimetre-wave spectrum, driven by demands from diverse applications including wireless backhaul links for 5G mobile networks, radar sensors for advanced or autonomous vehicles, space deployed radiometers for remote sensing of climate change, security imaging (e.g terahertz body scanners), and medical diagnosis.

Advancement in these applications has led to an increased demand for accurate and traceable electrical measurements for devices and integrated circuits operating at these high frequencies.

This workshop reviewed the latest developments that are taking place for the three electrical measurement quantities, namely S-parameters, power and complex permittivity of dielectric materials, at millimetre-wave and terahertz frequencies.

Most of these activities are undertaken in the EMPIR TEMMT project (http://projects.lne.eu/jrp-temmt/) which involves 19 global partners. 

Xiaobang Shang, Senior Research Scientist, NPL states:

The workshop has presented the current state of the art of electrical measurements at millimetre-wave and terahertz frequencies. There are growing demands for accurate measurements at these high frequencies, driven by notable applications such as 5G communications, radar sensors for autonomous vehicles, and space deployed radiometers for Earth monitoring. A large scale EMPIR project TEMMT, led by NPL, has been funded to tackle measurement challenges at these high frequencies. This workshop was devoted to the outputs from activities undertaken during the first half of TEMMT. We look forward to reporting more exciting results in the near future before the project finishes in middle 2022.
