Abstract
The theoretical and practical considerations are given of a coaxial line cell which enables the permittivity of aqueous liquids to be measured up to 4 GHz and that of non-aqueous liquids to be measured at higher frequencies. The paper includes brief details of the basic experimental and computational procedure used. The effects of wall loss are considered in detail and the appropriate corrections to the real as well as the imaginary part of the complex permittivity are explained.Keywords
