Abstract
Advanced manufacturing is becoming more widespread, offering finer control over parts and significantly improving material properties. Techniques like direct energy deposition and powder bed fusion allow for the creation of complex geometries, such as cellular lattice structures, which demonstrate impressive mechanical and thermal performance. These features make them ideal for next-generation lightweight and multi-functional engineering applications. However, existing characterization methods, including X-ray, optical and mechanical techniques, struggle to accurately measure dimensions, phase and composition within manufacturing-relevant timeframes, even for simple geometries and materials. This highlights the need for new, reliable and robust nondestructive measurement techniques that will be crucial for future manufacturing processes.
In this talk, Mukherjee will explore various electromagnetic modalities, ranging from static and quasi-static to dynamic wave propagation frequencies, for a broad range of diagnostic applications.
