Abstract :
A microwave system for measuring the thickness of dielectric materials employing the heterodyne technique is described. Calibration curves relating the dc output voltage and dielectric thickness are presented for leather, glass, and cartons. The system was operated at 9 GHz. The experimental results illustrate the suitability of the technique for industrial applications.
