“…The dielectric properties measurement system consists of three parts: a network analyser (Model E5062A, Agilent Technologies, Santa Clara, CA, USA), as well as an open-ended coaxial probe, together with a calibration kit (Agilent Technologies, Palo Alto, CA, USA), including a hightemperature coaxial cable, and a Agilent 85070E dielectric probe kit. The system was calibrated before each set of measurement because of small variations in the cable position, connections, ambient temperature and other factors can affect the performance of the system (Al-Muhtaseb et al, 2010). The calibration operation was carried out by taking dielectric measurements for three known standards: namely air,a shortening block and distilled water at the required temperature, as prompted by the dielectric probe kit software (Model E5062A; Agilent Technologies).…”
