Numerical Computation of Dispersion Relations for Multi-layered Anisotropic Structures

Center of Advanced European Studies and Research, DE

Keywords: dispersion relations, surface acoustic waves, multi-layered structures, linear elasticity

Abstract:
The paper presents an algorithm and a program for the computation of the propagation velocity of acoustic waves excited in anisotropic multi-layered structures. This investigation is motivated by the modeling of a biosensor that serves for the detection and quantitative measurement of nanoscopic amounts of biological substances. The program is supplied with a user friendly graphical interface and can be useful for researchers working on acoustic sensors. The simulation results are in a good agreement with experiments.
