摘要： An acoustic delay line device for microwave equipment includes a cylindrical acoustic substrate. A transducer array including four transducers located at the corners of a square is formed on each end of the cylinder. The four transducers are electrically connected in series top-to-top and bottom-to-bottom so that adjacent transducers are of opposite polarity and dipoles are formed diagonally. The first and last transducer in the series are connected electrically to the outside source of receiver of RF signals by bonding pads which are offset from the transducers, and by connection wires bonded to the bonding pads. A ground plane area is provided on both ends of the acoustic substrate surrounding each transducer array.

摘要： Comb filter having a comb like band pass characteristic curve by using an ultrasonic delay line (9) is improved to reduce its size. An input signal is given through an impedance element 13 to a single terminal 10a of an improved delay line 9, wherein the single terminal serves as the input terminal and at the same time as the output terminal. Signals at both ends of the impedance element 13 are given to a mixing circuit 15 for summing or subtracting thereby. In the improved delay line 9, the ultrasonic wave radiated from the input terminal travels twice the conventional delay line and comes back to the original terminal, and thereby a sufficient propagation distance is obtainable in a small delay line.

摘要： An acoustic surface wave interaction device includes a plate of dielectric material provided with two transducers each having at least one pair of comb-shaped electrode arrays having a plurality of teeth. The teeth in one comb-shaped electrode array of each pair are interleaved with the teeth of the other comb-shaped electrode array. At least one transducer has the pair of comb-shaped electrode arrays divided into two or more pairs of comb-shaped electrode arrays which are electrically connected in series, while the length of teeth is varied so that the tip ends thereof are enveloped by a curve representing the inverse Fourier transform of the transfer function of the device. The number of pairs of interleaving teeth to be included in one divided pair of electrode arrays is determined by the length of interleaving of the teeth in order to provide each divided pair of electrode arrays with the same impedance.

摘要： A device for processing electromagnetic wave energy by converting the wave energy to spin waves and/or elastic waves, the present disclosure being particularly directed to the concept of providing a device made up of a single-crystal material which contains non-uniform material parameters to give graded values of material saturation 4 pi Ms. The material discussed in greatest detail is YIG and the non-uniform material parameters are furnished by doping the YIG with gallium. The graded material parameters in combination with an external magnetic bias field H result in an internal magnetic bias field H. The electromagnetic energy as it enters the material is acted upon in a manner that is influenced greatly by the contour of H. The contour of H in the present disclosure, in turn, is predetermined to present gradations in H which will allow the conversion mentioned and which allow predetermination of the wavenumber k of the magnons and/or phonons thereby formed. Furthermore, the place or space within the crystal at which conversion occurs can be somewhat determined by the profile of H thereby provided.

摘要： The present invention relates to a device for deflecting magnetic waves. According to the invention, there is provided a system comprising a plate of ferrimagnetic material polarized by a magnetic field H, wherein magnetic waves are excited. An arrangement constituted by a serpentine wire conductor lying on an insulating plate, periodically modulates the magnetic polarizing field in a zone underlying said arrangement, the latter induces a diffraction grating disposed in such a way that the magnetic waves arrive on it at the BRAGG angle. A controllable current source 6 supplies the wire conductor.
