Abstract :
Numerical analysis of acoustic wave propagating in YZ lithium niobate covered by ideal periodic metal strips is presented. Mathematica package has been found convenient for the analysis. Graphical results are presented for surface acoustic wave velocity and for the generating efficiency of strips for wide range of metallization ratio and frequency
