Some Recent Advances in Measurements at Millimeter-Wave and Terahertz Frequencies: Advances in High Frequency Measurements

The millimeter-wave (mm-wave) and terahertz (THz) regions of the electromagnetic spectrum are seeing increasing prominence, with a range of established and emerging applications—wireless backhaul for mobile networks for 5G and 6G infrastructure, automotive radar sensors, space-deployed radiometers for Earth observation, climate monitoring, weather forecasting, and more—exploiting these frequencies. Measurement techniques informed by the latest metrological research into the measurement of electrical quantities underpin the development of components and circuits for such applications by enabling the accurate and consistent measurement results to be obtained.
