摘要： A reflective grating (18) having spaced grid lines (36) patterned on a piezoelectric substrate (12) for controlling the magnitude and phase of surface acoustic waves (28) in a reflective filter (10) or resonator. The magnitude and phase of the surface acoustic wave (28) are controlled by a sampling period (34) of the reflective grating (18) and the density and sequence of distributed acoustic reflective dots (42). The reflective dots (42) are randomly distributed within gaps (40) between adjacent grid lines (36) or on top of the grid lines (36) of the reflective grating (18). The pattern of the reflective dots distributed within the gaps (40) or on the grid lines (36) is determined by the dot density, where the dot density varies from a lowest density of 0 to a maximum density of 1.

摘要： A surface acoustic wave element includes a piezoelectric member, a comb-teeth electrode, and a reflector. The comb-teeth electrode is arranged on the piezoelectric member. The reflector is arranged on the piezoelectric member. The reflector reflects a surface acoustic wave transmitted from the comb-teeth electrode. The reflector has a plurality of areas, and each of the areas has a frequency to make a reflection efficiency the largest. At least two of the frequencies of the areas are made different from each other.

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 νFMR the ferromagnetic element (106) is absorbed well and the magnetization 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.

摘要： A gyroscope comprises a piezoelectric substrate having a surface. Disposed on the surface are a resonator transducer, a pair of reflectors, a structure such as a metallic dot, and a sensor transducer. The resonator transducer creates a first surface acoustic wave on the surface. The pair of reflectors reflects the first surface acoustic wave to form a standing wave within a region of the surface between the pair of reflectors. The structure is disposed on the surface within the region, wherein a Coriolis force acting upon the structure creates a second surface acoustic wave. The sensor senses the second surface acoustic wave and provides an output indicative thereof.
