Abstract In many fields of applied
research interest exists for wideband dielectric characterization of liquid materials;
for example, aqueous solutions of biological materials. For this purpose a
particular procedure is proposed, based on the use of a Vectorial
Network Analyzer and a suitably designed reflection test cell which contains
the material under test. Fundamental features of this method are: (1)
dielectric characterization directly in the frequency domain without the use
of a Fourier inverse transformation process, as required when Time Domain Reflectometry (TDR) techniques are used; (2) wide-band
measurement in a very short time; (3) the need for much less test material
than required by commercial dielectric probes. Key Words: Dielectric
characterization, Dielectric probe, Dielectric relaxation spectra, Test of
biological materials. |
