Modeling temperature sensitivity of STW using Lagrangian material constants

This paper details the computation of the speed of surface transverse waves on periodically corrugated surfaces with help of the effective lagrangian material constants referred to the natural state of the crystal. The main benefit of the method is that, at the difference of commonly encountered methods based on the perturbation theory, it allows in a single pass for a direct computation of the temperature sensitivity of the speed or of the delay up to the third order in terms of temperature, thereby giving access to the modeling of the location of turn over points in temperature-compensated cuts.
