In the program description Don Thompson mentioned that one of the overall objectives was to try to increase the communication between the basic research community and the NDE user, and I'd like to mention that my own involvement in NDE did not come from a specific problem oriented research project in NDE. In fact , my interest in electromagnetic generation began from some physics problems, particularly with studies of the electronic properties of potassium single crystals at liquid helium temperature where the contactless feature of electromagnetic transducers was a useful advantage.
