title = "Application of air-coupled sensors to surface wave NDT in concrete",
abstract = "This paper reviews the progress of air-coupled surface wave sensing methods in NDT of concrete structures. The theoretical background of air-coupled sensing and its applications to surface wave measurement are discussed. The theoretical analysis shows that air-coupled sensors are able to detect leaky surface waves that are excited by a transient point load in concrete. The air-coupled sensing technique can be used to measure surface wave dispersion curves with SASW and MASW approaches, and to image defects in a concrete slab by measuring surface wave transmission ratio. Experimental results show that air-coupled sensors are able to replace contact sensors in traditional surface wave tests, and therefore greatly improve test efficiency.",
