Abstract

An eddy current probe using self-similarity fractal structure Koch curve excting coils is first proposed. Its working principle and theoretical model are deeply analyzed. The analysis shows that, due to eddy current counter effect in multiple places, the counter effect becomes more apparent and the eddy current density becomes stronger, with increasing stage of Koch curve. The exciting result and the sensitivity of eddy current probe are significantly improved, so the detection capability for micro-defect is improved. These results are validated by experiments of real system.
