About

Riichi Murayama has made pioneering contributions to the field of non-destructive evaluation (NDE), with a particular focus on ultrasonic inspection technologies. His key research areas include the development of advanced electromagnetic acoustic transducers (EMATs) and robotic systems for structural health monitoring. Murayama’s most notable work, "Development of an ultrasonic inspection robot using an electromagnetic acoustic transducer for a Lamb wave and an SH-plate wave" (2004), has garnered 57 citations, reflecting its influence in the NDE community. This paper introduced a novel robotic platform that integrates EMATs to generate and detect Lamb waves and shear horizontal (SH) plate waves, enabling efficient and contactless inspection of plate-like structures. His contributions have advanced the practical application of guided wave techniques for detecting defects in industrial components, such as pipelines and storage tanks. Murayama’s work is particularly valued for its emphasis on automation and real-world deployment, bridging the gap between laboratory research and field inspection. His achievements have been recognized through collaborations with industry and academia, and his research continues to inspire innovations in smart sensing and robotic NDE systems.
