The technique is based on the spectrum decomposition method and was investigated in the case of A<sub>0</sub> and S<sub>0</sub> modes of Lamb waves propagating in CFRP composite plate. The obtained measurement results were compared with the theoretical dispersion curves obtained by SAFE method.<p>DOI: <a href="http://dx.doi.org/10.5755/j01.eee.19.2.3470">http://dx.doi.org/10.5755/j01.eee.19.2.3470</a></p> ER -
