Complex Dielectric Constant and Dissipation Factor of Foliage,
Abstract
The report presents data on the dielectric properties of living foliage, plant material, and clay soil. This data is of potential value to investigators concerned with the effects of plant material and earth on electromagnetic radiation at radio and microwave frequencies. The report includes a description of the measurement theory and equations, experimental apparatus and techniques, a calibration check using water as a reference material, a discussion of sources of error and experimental data on a variety of specimens at 23C and over a frequency range of 10,000 Hz to 4.2 x 10 to the 9th power Hz. Estimates of precision, calculated from experimental data, are presented at representative frequencies. (Author)
