Paper Abstract

Transmission spectra were measured over the range 90-4200 GHz for a locally sourced soil sample composed mostly of quartz sand with ~200 micron particle size. A vector network analyzer covered the spectral range 90-140 GHz. A Fourier spectrometer collected transmission spectra over the range 120 to 4200 GHz. Transmission drops to zero for wavelengths shorter than the characteristic particle size of the sample as a consequence of scattering. Transmission spectra were also measured for various liquids in the 90-140 GHz and 450-1650 GHz ranges in the interest of index matching. These liquids were mixed with the soil sample and were found to reduce scattering and increase transmission through the soil at higher frequencies. This work is relevant to mine detection using THz and millimeter wave (mmW) radiation.
