摘要：
Finite difference-time domain (FD-TD) modeling method has been applied to study the interaction of concrete with electromagnetic waves. The purpose is to visualize the propagation of the electromagnetic fields in a dielectric medium of concrete to obtain one-dimensional images of a concrete target. A Gaussian pulse plane wave is directed to laboratory size concrete specimens as an excitation source. Geometry of the targets is varied with different dimensions, and with or without an inclusion.
