The aim of this work package is to go beyond the current state of the art in NSMM metrology on the microscale based on methods other than AFMs, with the intention of making them capable of traceable measurements on functional materials. This is being supported by the introduction of a wider range of modelling techniques for this type of NSMM measurement. Three new measurement modalities are being researched: (i) quantitative loss measurement, (ii) the use of TEM probes for measurement of anisotropy and (iii) the use of broadband probes. Methods will also be developed to quantify the spatial resolution of probes. Calibration artefacts will be used to evaluate spatial resolution. This will allow a comparison between simulation results derived from modelling software and measurement results obtained by two different techniques.
Partners RolesNPL leads this WP and brings extensive knowledge of microwave measurements especially in the area of electromagnetic materials.
ETHZ adds essential modelling experience to the work package.
Imperial College brings expertise in the application of 'transverse electromagnetic' (TEM) probes and will be responsible for developing a near field probe based on this technology. The probe will be integrated into the facilities at NPL
Links with other Workpackages (WPs)The modelling in this WP is closely aligned to that in WP1 and ETHZ will play a major role in both WPs.
The other WPs link to this WP through common requirements in modelling and measurement comparisons.
