Zusammenfassung:A system for non-destructive inspection of a structure includes a magnetostrictive strip, a plurality of coil circuits, a jacket assembly, and a tensioner. The magnetostrictive strip is configured to be induced with a bias magnetic field and wrapped at least partially around an outer surface of a structure. The plurality of coil circuits disposed on a flexible circuit board having at least two layers of conductive signal traces. The jacket assembly includes an inner jacket component, an outer jacket component, and a mid-layer component configured to be disposed adjacent to the plurality of coil circuits. The tensioner is configured to provide a mechanical pressure coupling between the magnetostrictive strip and the structure. Each coil circuit is individually controllable by a plurality of channels to at least one of excite or detect guided waves in the structure.
