The use of a combination of several measurement techniques to investigate the dielectric properties of 80 rock samples in the microwave region is discussed. The real part of the relative dielectric constant epsilon ' was measured in 0.1-GHz steps from 0.5 to 18 GHz, and the imaginary part epsilon " was measured at five frequencies extending between 1.6 and 16 GHz. In addition to the dielectric measurements, the bulk density was measured for all the samples and the bulk chemical composition was… Expand

Rock fraction effects on the interpretation of microwave emission from soils
TLDR
The effects of rock fraction are not significant in estimating the sample soil moisture when 21-cm data are used, and the presence of rocks will make this and shorter wavelengths useless as soil moisture sensors. Expand

Impact of Compressive Stress on Microwave Dielectric Properties of Feldspar Specimen
TLDR
It is implied that the variation of the microwave dielectric permittivity of rock mass under altering crustal stress due to tectonic plate movements and engineering disturbances is an important factor to be considered in applying radar investigation and microwave remote sensing for mineral exploration, geological exploration, and geo-hazard perception.
