Dielectric Measurements of Five Different Soil Textural Types as Functions of Frequency and Moisture Content.

摘要

Open-circuit coaxial transmission-line sample holders were used to determine the electromagnetic dielectric properties of five soil textural types as functions of moisture level content and frequency. A brief outline of the theoretical basis is given for the open-circuit method along with the measurement system and the sample preparation. Experimental results are given for the different soil textural types for moisture levels ranging from 0to 48percent and for test frequencies ranging from 300to 9300MHz.
