While the understanding of the properties of gratings is essential for any SAW design, high temperature stable electrodes, which are generally made of heavy materials, are not easily accessible by simulation. We have therefore studied this type of electrodes both experimentally and by simulation. Motivated by the demands made by SAW gas sensors operating at high temperatures we opted for a combination...
This paper describes the use of a general purpose modified simulator, first developed by K. Hashimoto to determine a priori the device responses of the specify Pt/LGS Y-X structure. The parameters for the analysis are determined as a function of the electrode type (physical constants, thickness) and substrate. The simulation responses are analyzed and compared to the experimental results and we should...
