Electrical Characterization of Glycerin: Water Mixtures: Implications for Use as a Coupling Medium in Microwave Tomography

Abstract: We examine the broadband behavior of complex electrical properties of glycerin and water mixtures over the frequency range of 0.1 – 25.0 GHz, especially as they relate to using these liquids as coupling media for microwave tomographic imaging. Their combination is unique in that they are mutually miscible over the full range of concentrations which allows them to be tailored to dielectric property matching for biological tissues. While the resultant mixture properties are partially driven by differences in the… Show more

“…The employed antennas are modifications of a previous 60 GHz design [16], which has been scaled and optimized. They are based on a 12x14 mm 2 patch with a substrate thickness of 254 μm, dielectric constant (εr) of 2.2, and loss tangent (tanδ) of 0.0009 (RT/duroid® 5880 Laminate by Rogers Corporation).…”

“…Tackling this problem with hardware depends on the type of application and system design. In microwave tomography, for example, the system is immersed in a highloss liquid which can suppress unwanted multipath propagation [15], [16]. However, this causes additional attenuation in the diagnostically useful transmitted signals, which would be prohibitive in shorter-wavelength mmwave applications such as glucose sensing.…”

“…Its permittivity can be varied considerably because it is soluble in water. It is nontoxic and ideal from a human safety prospective . The human chest model with fixed outer and different inner layer electrical properties are formed using a mixture of sodium chloride (NaCl), water, isopropyl alcohol (IPA), and glycerin.…”

“…The matching fluid is contained within a chamber whose walls are referred to as the MWI enclosure (or, casing). Depending on the OI, these matching fluids may be chosen to be canola oil [1], saltwater [2], glycerin-water mixtures [3], etc. Similar to indoor antenna ranges where measurements are performed in anechoic chambers, it is often desired to mitigate the reflections from the MWI enclosure.…”
