Description: The present study involves two semi-infinite homogeneous, isotropic, linearly elastic plates      perfectly bonded end to end. The plates have dissimilar material properties (e.g., copper and      aluminum). Incident on the interface are both the lowest symmetric and the lowest      antisymmetric Rayleigh-Lamb eigenmodes. The resulting transmitted and reflected fields      contain contributions from all of the real, imaginary and complex plate modes which are active      at the given excitation frequency. A study of the distribution of energy among the various      reflected and transmitted Rayleigh eigenmodes over a range of frequencies is undertaken for a      number of material combinations of the bimaterial plate.
