Our Publications

our dedication to fundamental research


Ultrasonics is the only internationally established journal which covers the entire spectrum of ultrasound research, technology and applications. Ultrasonics contains a variety of sections to keep its readers abreast of the state of the art in both fundamental investigation and real-world development related to ultrasonics. Ultrasonics publishes papers of exceptional quality and of relevance to both academia and industry. Manuscripts in which ultrasonics is the core and not simply an incidental tool or secondary issue are welcomed.

Editorial Role

Structural Health Monitoring: An International Journal is an international peer reviewed journal that publishes the highest quality original research that contain theoretical, analytical, and experimental investigations that advance the body of knowledge and its application in the discipline of structural health monitoring. The journal has a broad topical coverage and it serves as a primary reference for the structural health monitoring of aeronautical, mechanical, civil, electrical, and other systems. The multidisciplinary nature of the journal is intended to foster the intersection of different technologies to address the varied needs and applications for structural health monitoring.
