Electromagnetic nondestructive evaluation and testing encompasses a range of different specific methods that can be used in a number of diverse applications, from the detection and sizing of defects in metals, through to the quantification of subtle changes in the electromagnetic properties of a sample from the surface to bulk.
Electromagnetic NDE is one of the most practically viable methods used in both research and industry and in general, is a well regarded and established inspection and measurement method. Electromagnetic NDE continues to be an exciting area of research generating new results and ideas, and advances in computation are constantly helping to open new avenues of research. As an NDE or NDT method it produces new leading edge, scientific developments not only in academia, but also within industrial research teams.
As with the previous and highly successful special issue on Thermographic Testing, the aim of this Special Issue on Electromagnetic NDE is to take a ‘snap-shot’ of the state of the art from a wide selection of some of the key researchers involved in this area who were invited to submit papers to this special issue. Authors have also been encouraged to submit standard format research papers of previously unpublished work or papers that act as a review of the authors own work up to the current boundaries of their research area. We have tried to demonstrate a breadth of applications for which one can use Electromagnetic NDE, together with very recent research developments and some clear demonstrations of the method at work in various applications.
We are sure that readers from the electromagnetic and wider NDE community will find this a useful and informative Special Issue and also that they will find this is a valuable reference resource. Finally, and most importantly, I would like to thank the contributors and referees for the papers in this issue, without whose support it would have been impossible to collate such a focused and valuable scientific resource for current and future workers in this area.
