DOI: 10.1109/jsen.2025.3622986
Abstract: Ultrasonic interdigital transducers (IDTs) hold great promise for nondestructive testing (NDT) due to their tunable frequency and beam-focusing capabilities. Conventional ulrasonic IDTs are often constrained by narrow scanning angles and relatively low spatial utilization efficiency,… read more here.
