Abstract: Non-destructive evaluation (NDE) methods have dominated most of the fields of applied research and technology over the last twenty years. These techniques provide information on the functional efficiency of materials and structures without causing any structural impact on the structure itself. Their use enables the monitoring of the structural integrity, the structural condition as well as the service in-duced degradation of materials and structures during their service life. In this respect, they address a vast field of applications ranging from the aerospace and automotive industry to civil
