A Differential Excitation Eddy Current Probe Based on Novel Annular Fractal Curve for Defects Inspection

A flexible eddy current probe can detect the defects in components with a complex structure due to its bendability and adaptation to the surface of the tested specimen for nondestructive testing. However, the traditional, flexible eddy current probe with circular and rectangular coils may neglect sm...
