Area of Science:

  • Materials Science
  • Electromagnetics
  • Non-Destructive Testing

Background:

  • Cracks are common defects in metallic components, impacting service life and stability.
  • Electromagnetic resonator sensors offer high sensitivity but are limited in size for large-area monitoring.
  • Uneven internal field distribution causes sensitivity variations in conventional sensors.

Purpose of the Study:

  • To develop an electromagnetic resonator sensor for large-area crack detection in metallic structures.
  • To overcome the size limitations and sensitivity variations of existing sensors.
  • To utilize resonance frequency shifts for accurate crack identification.

Main Methods:

  • A vertical U-shaped ring resonator structure was designed and excited using a microstrip line.
  • The shift in resonance frequency was measured and analyzed as a characteristic feature for crack identification.
  • The sensor's sensitivity to crack depth and width was quantified.

Main Results:

  • The proposed sensor design enables large-area monitoring while maintaining high sensitivity.
  • The sensor achieved a measurement sensitivity of 0.95 GHz/mm² for crack depth and 0.685 GHz/mm² for crack width.
  • Resonance frequency shifts effectively characterize and identify cracks.

Conclusions:

  • The vertical U-shaped ring resonator sensor is effective for detecting cracks in metal structures.
  • This technology offers a promising solution for non-destructive evaluation and structural health monitoring.
  • The sensor overcomes limitations of traditional sensors, enabling broader application in industrial settings.
