Design scheme of an S0 wave-based low-pass wave filter and an A0 wave-based Luneburg lens in a graded stubbed plate

Owing to their ability to detect small defects and flaws at very low frequencies, ultrasonic guided waves, as well as their artificial manipulation in structural health monitoring and non-destructive evaluation systems, are generating growing interest both in scientific research and engineering appl...
