Measurement of Broadband Dielectric Properties of 10% Formalin and 1,4 Dioxane using Dispersive Fourier Transform Spectroscopy

The broadband dielectric properties of 10 % formalin and 1,4 dioxane are presented in this paper. A variable temperature, variable thickness interferometer was assembled to perform dispersive Fourier transform spectroscopy on liquids. Using the two thickness method, the refractive index, absorption coefficient, real and imaginary permittivity, and loss tangent were obtained as a continuous function of frequency from 60 to 600 GHz (2-200 cm). Knowledge of these properties can facilitate future research in examining certain tissues and mixtures. Tests on chlorobenzene were also conducted as a calibration reference
