A concrete-steel interface spectral element is developed to study the guided wave propagation along the steel rebar in the concrete. Scalar damage parameters characterizing changes in the interface (debonding damage) are incorporated into the formulation of the spectral finite element that is used f

## Abstract This article deals with a fast numerical method for GPR simulation of great scenes. Electromagnetic wave propagation in heterogeneous media is analyzed using a finite‐difference time‐domain (FDTD)‐based method. The use of a moving subdomain allows dealing with large scale and realistic
