The theoretical concept is based on the measurement of the dielectric contrast between water and the host material in the microwave frequency range, and is successful up to 2 cm in depth. In conservation, this method has been usefully employed for determining by non-invasiveway the moisture and salts content inside materials. evanescent-field dielectrometry (traducció pendent) evanescent-field dielectrometry (traducció pendent) 2026-03-30 20:25:30
