Due to the increased use of polymers in research and industry, the non-destructive determination of material parameters is gaining importance. In order to determine the material parameters of a polymer, transmission measurements through waveguide specimens can be evaluated. However, sensitivity analyses show a high uncertainty in the determination of the mechanical shear parameters. As a means to increase the sensitivity to these parameters, different excitations are investigated.
