N2 - A novel self-tuning technique for Lamb wave inspection especially appropriate for anisotropic materials such as some composites is presented. Propagation speeds for the different Lamb modes are in-situ tuned for the different directions, covering the whole azimuth range. By performing a frequency sweep, optimal frequencies for working with each wave mode are also selected. The proposed method is firstly evaluated by multiphysics numerical tests. Finally, the method is applied for locating a defect in a Fiber Reinforced Composite plate by reflection tomography.
