Abstract
In summary, the dissertation identified and solved two research challenges in ultrasonic pulse-echo nondestructive evaluation through both experimental and numerical approaches. The spatial sampling study will provide quantitative engineering guideline for real-time on-line package inspection implementation. The subwavelength defect detection mechanism study prompts our understanding about nondestructive characterization and evaluation of materials.
