Microwave Dielectric Behavior of Soils. Report 2. A Unique Coaxial MeasurementApparatus

摘要

A reflection/transmission laboratory apparatus and data collection methodologyare described that can be used to measure the complex dielectric response of moist soils over the 100 MHz-18 GHz frequency range. The experimental setup includes a square cross-sectional coaxial sample holder, a vector network analyzer system for signal generation and detection, and an external bath for sample temperature control. Data collected on liquids whose dielectric response is well known verify that the electrical property calculation algorithm functions properly.
