Complex permittivity spectra of binary polar liquids using time domain reflectometry

Abstract

The study of complex properties in a binary mixture of polar liquids has been carried out in the frequency range of 10[Formula: see text]MHz to 30 GHz at 293[Formula: see text]K and 298[Formula: see text]K temperatures using time domain reflectometry. The complex properties of polar liquids in binary mixture give information about the frequency dispersion in the dielectric permittivity ([Formula: see text]) and dielectric loss ([Formula: see text]). The information regarding the orientation of electric dipoles in a polar liquid mixture is given by Kirkwood parameters. The Bruggeman parameters are used as the indicator of liquid1 and liquid2 interaction. Molar entropy ([Formula: see text]) and molar enthalpy ([Formula: see text]) are also discussed at the end of the paper.

Dielectric Relaxation Studies of Hydrogen Bonded Complexes of Benzamide and Acetamide with Halogenated Phenols Using X-band Microwave Frequency

“…The microwave power is measured by the probe, which is a crystal detector. A sensitive spot galvanometer receives the microwave current (Tabassum and Pawar 2018). Many of the chemicals used here had their physical parameters tested against their literature values.…”
