Non-destructive dielectric characterization techniques using electromagnetic waves

Microwave characterization is an important tool to characterize different materials precisely and often non-destructively. Number of evaluation techniques have been implemented but the suitability and accuracy of each technique can be categorized as transmission and/or reflection methods, resonance methods and free-space methods. The measured dielectric properties of materials generally show discrepancies when data from free space, resonant cavity or transmission line measurements are obtained. This paper will discuss various methods used for the microwave evaluations of materials especially dielectric and metallic samples.
