  • Abstract
    The paper introduces an approach of discriminating the background media of concrete slab with reinforcing steel. The electromagnetic impact driving ultrasound is employed for high signal to noise ratio, and spectra of multireflected waves is analyzed. The theoretical analysis, the numerical simulation, and the experiment results show a same tendency of the varying of spectra with acoustic reflectivity on the interface of concrete and background media
