Microwave Dielectric Constant Dependence on Soil Tension.

Abstract

The purpose of this research is to determine the microwave dielectric behavior of soil through: (a) experimental measurements and (b) the development of theoretical models. To this end, dielectric measurements were made using waveguide and freespace transmission systems over the 1-2 GHz and the 4-18 GHz bands over a wide range of moisture for several soil types. The measured data were then used to (a) test existing theoretical models, (b) develop a new physical soil model, and (c) develop semi-empirical models. (Author)
