The Dielectric Spectroscopy Laboratory
Micro-Wave Dielectric Spectrometer

             This spectrometer allows to access the microwave range over a limited temperature range with a reasonable accuracy. (see an example below)

INSTRUMENT CHARACTERISTICS

Analyzer: Microwave network analyzer Agilent E8361A 

  • Frequency range: 2e7 - 7e10 Hz

  • Sensitivity better than tan(delta) ~1e-1


Dielectric probe: Dielectric probe kit Agilent 85070E

  • High temperatue probe: temperature range 250 - 470 K, Frequency range 0.2-20 GHz

  • Performance probe: temperature range 250 - 470 K, Frequency range 0.5-50 GHz


Temperature Control: Nitrogen-jet stream home-made system

  • Temperature range: 100 - 570 K

  • Temperature stability better than ± 0.1 K


Samples: Soft-solids and Liquids

  • The sample is placed in a cylindrical aluminum container of 20 mm diameter, and the dielectric probe is placed on  (or inside) the sample.
