Analytical time-domain model of transient eddy current field in pulsed eddy current testing

open access: yesActa Physica Sinica, 2010
The transient eddy current field is analytically modeled by applying inverse Laplace transform to pulsed eddy current testing. The closed-form solution to transient eddy current field in a complex domain is obtained by using the truncated region eigenfunction expansion (TREE) method and the theory of reflection and transmission of electromagnetic waves.
