A field campaign had been organized in August 2010 on Tüz Gölü salt lake, Turkey, with the aim of characterizing the site for satellite optical sensor vicarious calibration, and of comparing different methodologies of surface reflectance factor characterization. Several teams have made ground-based reflectance measurements with a field spectrometer on different areas of the salt lake of 100 m × 300...
Accurate measurements of dielectric properties of materials by the three-terminal air-gap method require accurate knowledge of the area of the electrodes. The expression giving the dielectric constant can be put in the form equation (1) where equation Equation (1) can be solved for A, giving equation The two fluid method enables us to measure the dielectric constant of a specimen without knowledge...
Recently developed transformer bridges have made it possible to easily make measurements of capacitance to a few ppm (parts per million), particularly at audio frequencies. The question naturally arises: can dielectric constant and phase angle measurements be made with comparable accuracy?
