June 2023: Section Meeting: Electromagnetic NDE: Breaking the diffraction limits

Presentation Title: Electromagnetic Nondestructive Evaluation: Breaking the diffraction limits, IEEE-APS Young Professional Ambassador Talk (ASNT Golden Gate Section)

Speaker: Saptarshi Mukherjee, Lawrence Livermore National Laboratory

Presentation Summary: Rapid evolution of sensor technology, computational resources, and data science has enabled advances in electromagnetic (EM) sensing and nondestructive evaluation (NDE) techniques. These techniques have relevance for a broad range of industries, such as aerospace, civil, environmental, biomedical, and advanced manufacturing. Despite these advances in technology, there remains a crucial need for the maturation of characterization techniques that allow for the rapid inspection of low-contrast objects with fine resolution at large standoff distances, as well as over large physical areas. In this talk, I will provide a summary of different EM systems spanning from the static to quasi-static to dynamic wave propagation frequencies, for a wide range of diagnostic applications. The EM NDE problem is multi-disciplinary in nature and engages development of forward and inverse solutions for new sensors, instrumentation, and computational methods for understanding the underlying physics. Specifically, I will be discussing: (1) real time imaging algorithms, (2) compact EM sensor systems, (3) numerical methods for accurate modeling of complicated environments and (4) signal processing techniques for improving the detection capability. This talk is affiliated with the 2023 IEEE Antenna & Propagation Society (AP-S)-Young Professional Ambassador Program. The objective of the IEEE APS-YP Ambassador program is to inspire, inform and involve AP-S Young Professionals on a variety of topics both technical and non-technical to enhance their interest and engagement in the field of Antennas and Propagation by delivering the talks at various chapters/sections virtually.
