Sh wave finite element
WebShear horizontal surface acoustic wave (SH-SAW) sensors have great application potential due to their advantages of easy integration, miniaturization and suitability in liquid environments. In this paper, the finite element method is used to analyse a new SH-SAW micro pressure sensor, in which there are many groove structures along the direction of … WebA method for the finite element computation of the s)·nthetic seismo gran1s of SH wave propagation in a two-dimensional (2-D) medium is pro posed.
