Electromagnetic near-field imaging of missing fibers in periodic fiber-reinforced laminates

Much work has been and is being carried out about the electromagnetic behavior of planar laminates (and in parallel, due to similarities of organization, of some particular photonic crystals) which are involving within each layer a periodic array of commonly orientated fibers, as it is underlined in [1] wherein many references on the topic can also be found, both in electromagnetics (and photonics) and elasticity.
