Abstract :
In this paper, we describe how microwaves can be used to detect surface micro-cracks on metallic surface. We propose a resonant probe based on the excitation of evanescent waves. We investigate the electromagnetic analysis of the probe when interacting with cracks and demonstrate its sensitivity to cracks. This theoretical demonstration is confirmed by experiment
