中文摘要:

在一个不对称的声学的传播系统的通带的控制数字地并且试验性地被调查,并且系统由一份期刊组成水里的矩形的栅栏和二个一致黄铜盘子。我们表明不对称的声学的传播的通带是仔细与栅栏时期有关,但是被黄铜板厚度稍微影响。而且,发射度能被同时调整栅栏时期和另外的结构的参数改进。系统的控制方法有更宽的频率范围和简单操作的优点,它在超声的设备有大潜在的应用程序。

英文摘要:

The controls of the pass-bands in an asymmetric acoustic transmission system are investigated numerically and ex- perimentally, and the system consists of a periodical rectangular grating and two uniform brass plates in water. We reveal that the pass-band of the asymmetric acoustic transmission is closely related to the grating period, but is affected slightly by the brass plate thickness. Moreover, the transmittance can be improved by adjusting the grating period and other structural parameters simultaneously. The control method of the system has the advantages of wider frequency range and simple operation, which has great potential applications in ultrasonic devices.
