Simulation of the magnetic field due to defects and verification using high-Tc SQUID

Rapid flaw depth estimation from SQUID-based eddy current nondestructive evaluation

“…We exploit this feature and show that a 2-D 'sheet inducer' geometry may be utilized to model experimental 'double-D' data to estimate the depth of an unknown flaw. The finite-element computations performed with the sheet inducer geometry were compared with experimental data obtained with a SQUID using a 'double-D' exciter reported by Jeng et al [2][3][4].…”
