Dielectric Relaxation Spectroscopy
2003Nowadays dielectric spectroscopy covers the frequency range from 10−6 Hz to 1010 Hz by using computer controlled impedance analyzers [1–10], network analyzers as well as time domain spectrometers [11,12]. At higher frequencies (above 10 GHz) one should use wave-guides, which means that for each frequency a separate apparatus is necessary to perform ...

Dielectric spectroscopy: Fashionable again
Advanced Materials, 1990The molecular dynamics of polymers and liquid crystals (see figure) affect the properties of these materials. The different modes of, for example, relaxation can be studied to great effect using a modern version of an old spectroscopic method—dielectric spectroscopy—which makes use of molecular dipoles to gain an insight into these processes.

Dielectric spectroscopy of ferroelectrics
Ferroelectrics, 1980Abstract Permittivity is one of some, most important pammeters characterizing physical properties of dielectric materials. The history of the investigation development of dielectrics traces some centuries back and is connected with the names of many outetanding scientists.

Dielectric spectroscopy of blood
Journal of Non-Crystalline Solids, 2002Abstract An experimental investigation of complex dielectric spectra of human blood in the frequency range 30 Hz–30 MHz has been carried out for various blood cell concentrations, temperature and environment. Electrode impedances and other distorting effects have been excluded.

Dielectric spectroscopy of semiconductors
1988. Annual Report., Conference on Electrical Insulation and Dielectric Phenomena, 2003The author proposes an interpretation of the dielectric response of semiconductors in terms of a screened hopping model relating both to the horizontal transitions in bulk material and to the vertical transitions in space charge regions and at interfaces.

Dielectric spectroscopy in agriculture
Journal of Non-Crystalline Solids, 2005Abstract Reported measurements of the dielectric properties or permittivities over broad frequency ranges for some agricultural materials are cited, and graphical data from the cited literature are presented. They include 50-kHz to 12-GHz frequency-domain permittivity data for adult rice weevils and hard red winter wheat, time-domain reflectometry ...

Multi-electrode dielectric spectroscopy
Chemical Physics, 1990Abstract The technique of multi-electrode dielectric spectroscopy is introduced to describe the molecular cross correlation dynamics of dipolar ensembles. The symmetry of the electrodes in the laboratory frame ( X, Y, Z ) is described with point group theory and is imparted to the ensemble dynamics in terms of new cross correlation functions in frame
