This book offers a comprehensive review of innovative measurement and monitoring solutions based on time domain reflectometry (TDR). This technique has numerous applications in several fields, ranging from the characterization of electronic devices to quality control of vegetable oils. However, most of the well-established TDR-based monitoring solutions rely on local or punctual probes; therefore, typically, to monitor large areas/volumes, a high number of probes must be employed, with the consequent maintenance and management requirements. On such bases, in the last few years, the authors...
