Electromagnetic Imaging of Damages in Fibered Layered Laminates via Equivalence Theory.

Electromagnetic nondestructive testing of damaged multilayer fiber-reinforced laminates is of concern. Each layer involves periodically positioned circular cylindrical fibers embedded within a matrix medium. Missing, displaced, shrunk, expanded fibers as well as circular inclusions inside a fiber are modeled as properly designed equivalent sources inside the undamaged structure. Then, the location...
