Abstract
A system includes at least one strip of ferromagnetic material and a plurality of pulsing/receiving coil circuits. The at least one strip of ferromagnetic material is induced with a bias magnetic field and is coupled to a surface of a structure under test. The plurality of pulsing/receiving coil circuits are aligned with a surface of the at least one strip of the ferromagnetic material. The plurality of pulsing/receiving coil circuits are individually controllable by a number of channels to excite guided waves in the structure under test using at least one of active phased-array focusing or synthetic phased-array focusing of the guided waves.
