| 摘 要： | Hashimoto有限元程序是日本Chiba大学研究人员从1973年开始、历时几十年用Fortran语言编写、计算声表面波在周期栅阵中传波特性的一个软件包。该程序能计算Rayleigh波、漏表面波、SH型表面波、表面横波等多种声表面波的传输特性，同时它能适用于一个周期内单根指条、两根指条和多根指条及声表面波在栅阵中斜入射的情况。该程序已在声表面波（SAW）研究人员中得到了广泛的应用。

| Abstract: | The Hashimoto＇s FEM program is a complete set of software written in the form of FORTRAN source codes, which was developed by Japanese researchers of Chiba university after spending several ten years from 1973 and used to calculate the properties of surface acoustic wave propagation in periodic metal gratings. The program can simulate Raylergh wave, leaky wave, SH-type SAW and surface transverse wave devices in the cases of single-electrode gratings, double-electrode gratings and tripleelectrode gratings. It is now widely used by SAW researchers. |
