The impedance method has been considered for the measurement of a dielectric permittivity and losses of water solutions of salts in the high-frequency band. The complex dielectric permittivity of solutions with different concentrations has been measured. The usefulness of the method for measuring dielect...
This paper reviews and evaluates the experimental works of the static dielectric constant (permittivity) of water and steam over the century. The critically evaluated experimental data are represented by a function of temperature and density. This representation was carefully examined in the light of ...
For the e-scenario, we employ the advantages of strong temperature dependence of the dielectric permittivity of water that is characterized by e ¼ 80 at 20 °C and e ¼ 50 at 90 °C in the microwave frequencies range from 1 to 6 GHz (refs 29,30). On the basis of the calculated...
Figure2presents the temperature-dependent radiofrequency (RF) spectra of the realε′(ν) and imaginaryε″(ν) parts of the dielectric permittivity of water molecules in cordierite measured for the polarizationE||a. Since the MHz–GHz reflectometric technique does not provide absolute values, the...
The dielectric permittivity of cementitious materials during 24 hours hydration period at a frequency of 2.45 GHz using a network analyzer with open-ended probe technique was measured. Influences of water-to-cementitious ratios, cement types, pozzolans and aggregate types are taken into consideration....

In fact, water has not attracted any attention of the scientific community as a building block for electromagnetic metamaterials until very recently21, only being employed for negative-index acoustic metamaterials22,23 during the past few years. Even though the real part of permittivity Re(ε) for...
