PERMITTIVITY ( DIELECTRIC CONSTANT ) OF WATER AT VARIOUS FREQUENCIES The permittivity of liquid water in the radiofrequency andSengers, Levelt
Dielectric constantof water is an important parameter affectingprotein adsorptiondue to its influence onintermolecular forces. For instance, thestrengthof the electrical double layer is affected by the value of dielectric constant. The frequency response of dielectric constant proves important in determining...
Pertinent statistical mechanical theory is combined with the available measurements of the dielectric constant of water at high temperature and pressure to predict that property at still higher temperature. The dielectric constant is needed in connection with studies of electrolytes such as NaCl/H2O at ...
The advent of precision microwave radiometry has placed a stringent requirement on the accuracy with which the dielectric constant of sea water must be known. To this end, measurements of the dielectric constant have been conducted atS-band andL-band with a quoted uncertainty of tenths of a perc...
(separation of charge) is not complete. Under such conditions, thedielectric constantappears to be less than that observed in a direct-currentcircuitand to vary with frequency, becoming lower at higher frequencies. During the alternation of polarity of the plates, the charges must be displaced ...
The frequency of the applied voltage also affects the dielectric constant. As the frequency increases, the dielectric constant becomes non-linear and its value decreases more rapidly as the frequency increases. At high frequencies, electric power loss increases. This is one reason why materials with...
