Background, Motivation and Objective It is desirable to gain a deeper understanding of the mass-loading phenomenon in micro-acoustic devices beyond customary brute-force application of the Finite Element Method (FEM). The gained insights are expected to allow the design of more accurate approximate techniques in addition to illuminating the underlying physical phenomenon itself. At last years conference a method was proposed which eliminated the corner-points from the analysis by applying the spectral domain Finite Difference Method (FDM) to the mass-loading problem in two dimensional (2D) models of rectangular metallic electrodes. The superiority of the method against an optimized FEM code was firmly established.
