Traditional broadband transmission method for measuring acoustic dispersion and
attenuation requires the measurement of the thickness of the specimen, the transmission
coefficient at the water–specimen interface, and the Fourier spectra of two transmitted
pulses. A new method has recently been developed that can determine both the thickness
and dispersion of the specimen by utilizing the phase spectra of two additional pulses
reflected back from the front and back surfaces of the specimen. In this paper, the method is …
