Measured electrical constitutive parameters of soil as functions of frequency and moisture content

The measured electrical constitutive parameters (effective relative permittivity and effective conductivity) for Georgia red clay are presented. These results are for the frequency range 50 MHz-1.25 GHz and for six samples with water contents by dry weight ranging from approximately 0-30%. These electrical parameters should be useful in designing and characterizing broadband systems whose performance is dependent upon or affected by the Earth, such as ground-penetrating radars
