    Finite frequency sensitivity kernels for microwave NDE of metal-composite joints

    Authors: ,

Abstract

Composites are being increasingly used in civil, military and aerospace applications due to their unique properties such as high strength, low weight, durability and corrosion resistance. The high sensitivity of microwaves towards dielectric composites can be utilized for nondestructive evaluation and structural health monitoring. We investigate the capability of the adjoint inversion method for microwave imaging of composites. The computed electromagnetic finite frequency sensitivity kernels derived from the adjoint technique are utilized for imaging disbonds and for providing structural integrity information of metal-composite interfaces.
