<p>In eddy current testing, a time-varying magnetic field generated by a current-carrying coil is coupled with an electrically conductive specimen. The interaction of the induced electromagnetic field with the part, specifically with its material properties and geometrical discontinuities, causes a change in the impedance of the same (transmit or driver) coil or a separate (receive or sense) coil. When a transmit-receive type probe is used, either with two concentric or side-by-side coils, both coils are placed on the same side of the part. The receiving coil couples with the material under test, but even more with the driving coil; therefore, this arrangement reduces discontinuity sensing capabilities of the technique. To interrogate over the full thickness of the part, it is proposed herein to emulate the through-transmission ultrasonic testing for eddy current inspections, with the driver and the receiver coils on opposite sides of the investigated part. A stationary, planar, large-diameter printed-circuit copper coil is mounted on the far side of the part or embedded in a multi-layer structure, while a pencil-type probe is employed to scan in a plane parallel to the part’s top surface. Either of the coils could be used for driving or sensing. and the coupling between the two coils is realized through the entire thickness of the evaluated part. With the planar coil as a driver and the pencil coil as a receiver, the depth of investigation is enhanced by the area of the excitation coil, while the resolution is improved by the scanning step and small diameter of the sensing probe. The work is a demonstration of the viability of through-transmission eddy current testing with structure embedded printed circuit board coils for in-situ condition monitoring of metallic structures.</p>
