Ultrasonic Guided Waves

Focusing on the scientific exploration of ultrasonic guided waves in solids, this Special Issue of Applied Sciences examines their essential role in nondestructive material characterization, including applications in inspection, quality assurance, and structural health monitoring. It encompasses various aspects such as phased array transducers, meta-materials for wave control, and signal processing techniques, approached through modeling, simulation, and experimental studies. A deep understanding of the waves' multimodal and dispersive nature, along with their distinct displacement profiles, is crucial for effective application.
