A Review of Measurement Capabilities at Millimetre and Submillimetre Wavelengths at the UK's National Physical Laboratory

This paper gives an overview of capabilities available at the UK's National Physical Laboratory (NPL) for measuring the scattering parameters (i.e. S-parameters) and material properties of devices operating at millimetre-wave and submillimetre-wave frequencies. The paper also reports on some current research activities aimed at extending these capabilities and addressing major measurement challenges at these high frequencies.
