Inspection and evaluation of conducting, magnetic and dielectric properties of materials without destroying them is very useful in industries. This paper has reported planar electromagnetic sensors, (i) meander, (ii) mesh and (iii) interdigital configuration for nondestructive applications. The characterization of three types of planar sensors has been studied and comparative performance has been evaluated based on their areas of applications and results are presented here.
- Mesh and interdigital type
- Planar electromagnetic sensors
- Pork belly cuts
- Saxophone reeds
