Bramanti M. A wide-band dielectric characterization system for liquid materials of interest in biology. Internal note IEI-B4-23, 1995.
In many fields of applied research the interest exhists for wide-band dielectric ,characterization of liquid materials, for example, aqueous solutions of biological materials. For this purpose a particular procedure is here proposed, based on the use of a Vectorial Network Analyzer and a suitably designed cell which contains the material under test. Fundamental features of this method are: dielectric characterization directly in the frequency domain without the use of a Fourier inverse trasfonnation process, as it it is required when TDR techniques are used; wide- band measurement in a very short time; the need of a quantity for the material to be tested far lower than those required by the actually available commercial dielectric probes.
