Abstract :
This paper is concerned with recent trends in inverse problems arising in electromagnetic nondestructive evaluation systems. First crack identification problem arising in eddy current testing is discussed. The crack identification problem is formulated as a parameter estimation of electrical conductivities in the materials. Secondly, an identification problem of material degradation is formulated as a nonlinear electromagnetic problem. This is formulated as parameter estimation of magnetic permeabilities.
