“…As a consequence, in such cases, the impedance value is different from that of the tested component without the defect. This property also makes it possible to identify conductive objects [ 10 , 11 , 12 ] and to determine their thickness [ 13 , 14 ], radius [ 15 , 16 ], magnetic anisotropy [ 17 ] or electrical conductivity [ 18 , 19 ].…”

“…According to Lentz’s rule, the secondary magnetic field is directed opposite to the primary field and thus causes a change in the impedance of the coil. This property makes it possible to detect defects in conductive objects [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ] and determine their geometric dimensions [ 20 , 21 , 22 , 23 , 24 , 25 ], magnetic permeability [ 26 , 27 , 28 ], or electrical conductivity [ 29 , 30 , 31 ]. The changes in the impedance components of the sensor, and therefore the sensitivity of the measurement, strongly depends on the frequency of the current that excites the eddy currents and on the geometry of the sensor.…”

“…Dodd and Deeds explained an analytical model of an infinite half-plane for an axially symmetric eddy-current problem [ 17 ]; Du et al, implemented a metal classification method for planar metals using real and imaginary trajectories of mutual inductance change [ 18 ]; Liu et al, considered the case of tilted planar metals leading to lift-off variations and extracted the characteristic slope of the normalized inductance trajectory on the complex plane to achieve the classification of tilted planar metals [ 19 ]; Yin et al, designed a coaxial triple-coil sensor and a compensation algorithm to eliminate the effect caused by lift-off on the peak frequency of the imaginary part of inductance change [ 20 ]. Theodoulidis et al, proposed a theoretical model for calculating the impedance between a coil and a conducting cylinder at an arbitrary position [ 21 ], and also proposed an analytical expression for the coil impedance due to a spherical work-piece consisting of concentric spherical shells, which can be used for nondestructive testing of spheres with arbitrary radial conductivity and permeability distributions [ 22 ]; Hu et al, proposed a linear eddy-current feature for determining the radius of a metallic sphere based on the analytical model of the sphere [ 23 ].…”
