Guided wave has been applied to a wide variety of non-destructive testing for a plate, bar and pipe, among others. In this study, we propose a wireless sensing system for the guided wave testing in structural components. The three-dimensional motion of the structural component can be visualized using the measured guided waves at a fixed position, which are individually excited at various positions. This method is based on the elastodynamic reciprocity theorem. Here, the validity of the visualization met...
