On electromagnetic modeling and imaging of defects in periodic fibered laminates

Abstract : Fibered laminates involving in each of their layers glass or graphite fibers embedded in periodic fashion within a given material matrix suffer from damages at production and in usage, and electromagnetic testing is a way to get proper information on them. This requires reliable computational modeling of undamaged and damaged structures, to understand their behavior and acquire synthetic data to input into imaging algorithms, properly developed as well, a first step before controlled laboratory studies and, upon proof of concept, real world. Tools, both of modeling and imaging, will be summarized in the exposé, and a host of examples given, from low frequency to resonance, as encountered in practice as a function of the structures to be tackled. Parallels with photonics will be drawn. Guidelines for further exploration in the realm of non-destructive testing and evaluation will also be provided.
