    The Wave Propagation and Metamaterials (WPM) Lab is a research team dedicated to uncovering fundamental mechanical relationships between structure and mechanical wave propagation. They study how the structure at different length scales lead to new ways to control how mechanical waves propagate in materials.

    They seek fundamental mechanics-based discovery yet they are driven by critical applications. This research team strives to understand how the concepts they study can be applied in real materials and structures. They place an emphasis on fabrication and experimental realization, as well as realistic material platforms. The Wave Propagation and Metamaterials (WPM) Lab has two main focus areas:

    Phononic Metamaterials: Their goal is to design new materials and structures that can control mechanical waves in unprecedented ways. They take a holistic modeling-experimental approach, integrating simple physics-based analytical models, high-fidelity simulations, advanced manufacturing, and experimental wave mechanics. Our current thrusts include:

    Ultrasonic NDE: The main goal of this aspect of their research is to understand the relationship between microstructure and the ultrasonic response, in order to develop new methods of NDE. Their approach is primarily experimental, integrating advanced ultrasonic measurements with comprehensive micro-structural analysis and mechanical testing. Current thrusts include:
