Computation of Dielectric Constant and Loss Factor of Water and Dimethylsulphoxide from 0.1 to 13 GHz

This study examined the computation of the dielectric constant (ε') and dielectric loss factor (ε'') of water and dimethylsulphoxide (DMSO)at temperature 20oc, 30oc, 40oc and 500C within the frequency range of 0.1≤f≤13GHz using Debye equations. The Debye equations were derived, and the experimental values of the static dielectric constant (ε_s), dielectric constant at high frequency (ε_∞) and the relaxation time (τ) of water and DMSO at those temperatures were substituted into the derived equations and the dielectric constant (ε') and loss factor (ε'') of water and DMSO were computed with aid of maple-13 and results were generated. These results revealed that the method is capable of reproducing good results forwork done using single Debye and that of the reflection cell ofdimethylsulphoxide.
