Abstract: Wave‐mode separation is a critical step in anisotropic elastic‐wave imaging. To avoid high computational costs and additional corrections, we apply a separation formula in the space domain that projects Cartesian components of the elastic wavefield… read more here.

DOI: 10.1177/1475921719890590
Abstract: The Lamb wave inspection has emerged as a promising method for structural health monitoring and nondestructive testing. However, because of the highly dispersive and multimodal features, the Lamb wave mode separation has become a challenging… read more here.

DOI: 10.1177/14759217251380767
Abstract: In the absence of undamaged signals as reference signals, the conventional mode separation and recognition methods for aliasing ultrasonic-guided waves signal often lead to issues, such as the inability to separate weak damage signals, inaccurate… read more here.
