Tasks
Scattering parameters or S-parameters are the most commonly used tool in microwave network analysis. Since in microwave circuits conventional currents and voltages do not always exist, scattering parameters are defined via forward and backward traveling waves. Scattering parameters are most commonly measured by vector network analyzers. Vector network analyzers must be calibrated before they can measure scattering parameters accurately.
The working group Fundamentals of Scattering Parameter Measurements investigates possibilities to increase both the frequency range and the range of applications of classic s-parameter measurement techniques for linear and passive one- and two-port circuits:
- modeling of connector influences and surface roughness effects
- calculable calibration standards for higher frequencies
- electronic calibration units
- multiport measurement techniques
