A NEW METHOD FOR EVALUATION OF THICKNESS AND MONITORING ITS VARIATION OF MEDIUM- AND LOW-LOSS MATERIALS

By U. C. Hasar

Full Article PDF (968 KB)

Abstract:
In this research paper, we propose an amplitude-only method for unique thickness evaluation of medium- and low-loss materials. The method is based on using amplitude-only measurements at different frequencies to evaluate the unique thickness. Main advantages of the method are a) it eliminates the necessity of repetitive measurements of different-length materials to evaluate the unknown thickness of the same type material and b) it determines the thickness at any desired frequency in the band. Because the method uses amplitude-only measurements and enables the thickness evaluation at any frequency, it can be a good candidate for thickness evaluation of materials in industrial-based applications.
