Special Issue Information
Dear Colleagues,
Ultrasonic and electromagnetic nondestructive testing technologies are widely used in the industrial field. They evaluate material properties and structural integrity through nondestructive means.
Specifically, ultrasonic testing uses high-frequency sound waves as a medium and is thus suitable for detecting internal defects (such as cracks, pores, and delamination) in materials such as metals, composite materials, and ceramics; it has strong penetration and can accurately locate the three-dimensional information of defects. Electromagnetic testing (including eddy current, microwave, terahertz, and infrared technologies) is based on the interaction between electromagnetic waves and materials; it supports non-contact measurement and is suitable for identifying abnormal structures on the surface and near-surface defects of conductive and non-conductive materials.
The advantages of ultrasonic and electromagnetic nondestructive testing complement each other, and they are both rapidly developing towards intelligence, high precision, and multi-field fusion. For ultrasonic testing, to improve defect resolution and detection efficiency, it will develop towards phased array and full-focus technology; further research work needs to be carried out in multi-channel collaborative imaging and deep learning algorithm fusion to achieve intelligent recognition and the classification of complex defects. Electromagnetic testing will develop towards multi-frequency/pulse eddy current technology, the miniaturization of millimeter wave and terahertz detection equipment, and the quantitative evaluation of layered defects and micrometer scale defects.
This Special Issue welcomes theoretical and practical contributions aimed at further understanding ultrasonic and electromagnetic nondestructive testing technologies, including (but not limited to) high-resolution detection, multidimensional imaging, image processing, and data fusion. In addition, it also seeks reports on quality assessment in specific application scenarios with ultrasonic and electromagnetic nondestructive testing technologies.
We look forward to receiving your contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
