摘要：本发明提供的反射栅阵金属点阵精确加权的声表面波谐振器，包括压电基片，在所述压电基片上溅射金属叉指换能器和反射栅，反射栅包括分别设置在金属叉指换能器左右两侧的第一短路栅和第二短路栅，所述第一短路栅和第二短路栅在所述金属叉指换能器左右两侧对称分布，在第一短路栅和第二短路栅设置加权函数加权的金属点阵，在相邻两根反射栅条之间金属点的间距大于或者等于谐振器中最小相邻两根反射栅条之间的间距。本发明的有益效果是在第一短路栅和第二短路栅上设置函数加权的金属点阵的基础上，通过增大反射孔径，减小由于反射孔径过小衍射严重从而影响反射精度的问题，实现金属点阵加权更加精确，进一步旁瓣抑制，提高SAW谐振器的频率响应性能。

摘要： The present invention relates to a device and corresponding method for ultrafast controlling of the magnetization of a magnetic element. A device (100) includes a surface acoustic wave generating means (102), a transport layer (104), which is typically functionally and partially structurally comprised in said SAW generating means (102), and at least one ferromagnetic element (106). A surface acoustic wave is generated and propagates in a transport layer (104) which typically consists of a piezo-electric material. Thus, strain is induced in the transport layer (104) and in the ferromagnetic element (106) in contact with this transport layer (104). Due to magneto elastic coupling this generates an effective magnetic field in the ferromagnetic element (106). If the surface acoustic wave has a frequency substantially close to the ferromagnetic resonance (FMR) frequency VFMR the ferromagnetic element (106) is absorbed well and the magnetisation state of the element can be controlled with this FMR frequency. The device can be used in an RF-magnetic resonator, a sensor and a camera. The corresponding method can be used for ultrafast reading-out and switching of magnetic components and in magnetic logic.
