提出了一种新的确定声表面波和漏声表面波特性的数值方法。采用绿色函数法对周期电压驱动的无限大周期换能器进行了数值模拟。我们表明，模式参数的耦合和色散关系可以提取的导纳的变化作为驱动电压的周期性略有移位。这里首先介绍的方法导致显着节省计算时间。
A novel numerical method for determining the surface acoustic wave and the leaky surface acoustic wave characteristics is proposed. The Green's function method is used to simulate an infinite periodic transducer driven by a periodic voltage. We show that the coupling of modes parameters and the dispersion relation can be extracted from the change in the admittance as the periodicity of the driving voltage is slightly shifted. The method first introduced here leads to significant savings in computing time.
