On Quantifying State Variables of Soils Using Electromagnetic Methods

It is the wishful thinking of every soil engineer and soil scientist to be able to measure the required state variables to entirely describe the prevalent condition of a soil from both, the mechanic and hydraulic point of view. The presented contribution discusses and highlights possibilities opened up with electromagnetic methods to quantify these parameters based on different approaches, which involve sophisticated analysis methods of the measured dielectric spectrum and the intelligent use of sensing transmission lines.
