摘要： Magnetostrictive rod filter whose attenuation versus frequency curve has a resonance as the conventional magnetostrictive rod filters but also a pole at a frequency near the resonance frequency. The filter comprises a freely vibrating magnetostrictive rod, two windings symmetrically located with respect to the rod center and surrounding the rod, ferrimagnetic material sheaths surrounding the windings except on the parts thereof facing the rod and means for applying a d.c. magnetic field to the rod. The pole of the attenuation curve is due to a demagnetizing field created by portions of the rod externally projecting beyond the windings and by apertures in those parts of the sheaths facing these rod projecting portions.

摘要： An electromechanical converter of flexural vibrations used, for example, in electromechanical filters in the field of radio engineering, comprising a disk-shaped resonating element and a transducer element for converting electrical vibrations into mechanical and mechanical vibrations into electrical, wherein said converter features increased stability to the effect of mechanical loads and is easily tuned to the desired frequency. The transducer element takes the form of a ring of piezoelectric material disposed on the periphery of the disc engaging asymmetrically with respect to a central plane of the disc which is transverse to the axis thereof. A manipulation of the extent of asymmetry and the axial dimension of the ring provides an optimal arrangement and a control on the parameters of the converter.

摘要： An improved surface acoustic wave device includes a film of a magnetostrictive material disposed on a substrate and spaced apart input and output transducer elements disposed on the film. The input element causes horizontally polarized shear waves to propagate along the film via the magnetostriction of the film. The shear waves propagating along the film are received by the output transducer element. The SAW device can be integrated on a microelectronic circuit useable in single chip radio frequency applications.

摘要： A surface acoustic wave reflective array of the kind in which parallel rows of scatterers produce Bragg reflection of an incident wave in a wanted direction at a given frequency determined by the row spacing. The rows (4) are formed of scattering centers, eg metallized dots (11) divisible into unit structures (10) each containing a group of at least two such centers; the orientation and relative spacings (in terms of the Bragg wavelength) of the centers within each unit, relative to the direction (Z) of an incident beam, are such that the scattered waves constructively interfere in the wanted direction (X) while avoiding constructive interference in other directions. The scattering centers of each unit structure may be in the same row or in adjacent rows. The invention alleviates a disadvantage of existing reflective dot arrays, which tend additionally to produce reflections in unwanted directions.
摘要翻译：这种类型的表面声波反射阵列，其中平行的散射体行以由行间隔确定的给定频率在期望方向上产生入射波的布拉格反射。行（4）由散射中心形成，例如可分为单元结构（10）的金属化点（11），每个单元结构（10）包含一组至少两个这样的中心; 相对于入射光束的方向（Z），每个单元内的中心的取向和相对间隔（以布拉格波长为单位）使得散射波在有意的方向（X）上建构性地干扰，同时避免建设性干扰其他方向。每个单位结构的散射中心可以在同一行或相邻行中。本发明减轻了现有的反射点阵列的缺点，其倾向于在不想要的方向上产生反射。
