- HP has a "transducer" and software that hook up to a HP8510 Network
- Analyzer. This is for doing dielectric measurements with a
- contact probe. Note that this requires a substantial, i.e. probably not
- sputtered, amount of material. Also, the HP85071A software uses a NIST
- based alogrithm for doing complex permittivity and permeability
- measurements for samples in a coaxial air line. Lowest frequency is
- in the 200 - 500 MHz region. The frequency region from 10 MHz to 100 MHz
- seems to be the hardest to characterize since one can not ignore the
- finite
- extent of the sample and yet the phase change through the sample is
- not significant relative to instrumentation errors, at least in my
- experience.
