Workpackages

WP1: Traceable connectorized S-parameter measurements

WP leader: NPL

Other participants: LNE, PTB, BHAM, Chalmers, Anritsu, INTI, VDI

Objective: The aim of this work package is to develop metrological traceability and verification techniques for S-parameters (that measure the loss and phase change for transmitted and reflected signals) in both coaxial line (using the 1.35 mm E-band connector to 90 GHz) and rectangular metallic waveguide (using waveguides covering frequencies from 330 GHz to 1.5 THz).

Structure – the WP is divided into 3 Tasks:

  • Task 1: Coaxial dimensional traceability
  • Task 2: Coaxial electrical traceability
  • Task 3: Waveguide electrical traceability

 


WP2: Traceable planar S-parameter measurements

WP leader: VSL

Other participants: NPL, LNE, PTB, Chalmers, FVB, ULILLE, Anritsu, FormFactor, Keysight

Objective: The aim of this work package is to develop traceability and verification techniques for on-wafer measurements to cover frequencies from 110 GHz to 1.1 THz.

Structure – the WP is divided into 4 tasks:

  • Task 1: Reference calibration substrates
  • Task 2: Calibration, verification and measurement techniques
  • Task 3: Uncertainty sources and uncertainty calculation
  • Task 4: Traceable calibration and verification measurements

 


WP3: Traceable power measurements

WP leader: PTB

Other participants: NPL, GUM, LNE, METAS, TUBITAK, BHAM, Chalmers, WAT, R&S, VDI

Objective: The aim of this work package is to establish traceable power measurements in two selected frequency bands using rectangular metallic waveguides within the frequency range from 110 GHz to 750 GHz. This includes the development of waveguide calorimeters, the associated power sensor transfer standards and the transfer of traceable free-space power measurements to waveguide power measurements.

Structure – the WP is divided into 4 Tasks:

  • Task 1: Development of waveguide calorimeters
  • Task 2: Development of millimetre-wave power transfer standards
  • Task 3: Linking free-space to waveguide power measurements
  • Task 4: Comparison of power measurements

 


WP4: Traceable measurement of material properties

WP leader: METAS

Other participants: NPL, CMI, GUM, LNE, WAT

Objective: The aim of this work package is to develop traceability and verification techniques to measure material properties, i.e. complex permittivity and loss tangent, to 750 GHz. At least two waveguide bands will be covered (i.e. 140 GHz to 220 GHz, and, 500 GHz to 750 GHz) and different methods will be used to compare the results and establish the traceability.

Structure – the WP is divided into 4 tasks:

  • Task 1: VNA-based material properties measurement
  • Task 2: Optical methods for material characterisation
  • Task 3: Resonant methods for material characterisation
  • Task 4: Comparison of material parameters measured by different systems
