In the field of nondestructive inspection by eddy current testing, various approaches to the depth-sizing of SCCs by numerical inversion analysis have been taken so far. However, its accuracy is not so high and limited to a certain extent because of no information about the real value of inner conductivity of SCCs. Therefore, we first investigated experimentally the inner conductivity distribution of several artificial SCCs by a precise mechanical processing and 4 terminal resistance measurement. From ...
