Microwave Absorption Measurements and Interference Effects for a Liquid Fuel between 2.5 and 18 GHz
Abstract
The incident, reflected and transmitted powers were measured and the reflection and transmission coefficients calculated for a liquid fuel. Two sizes of double-ridge waveguide were used to cover the frequency ranges 2.5 to 7.5 and 7.5 to 18 GHz and corrections were made for waveguide losses. Strong interference effects were observed and the real part of the dielectric constant was obtained primarily from the separation of interference maxima and minima. The loss tangent was obtained by curve fitting to the normalized power loss, and the absorption coefficient was calculated as a function of frequency from the dielectric data....
