摘要： A non-magnetized ferrite material is provided as the propagating medium for a microwave transmission line such as a microstrip or stripline transmission line. The transmission system is adapted to provide a "high pass" filter characteristic by selecting the saturation magnetization of the ferrite as a function of the desired cut-off frequency such that frequencies below the cut-off are absorbed by the ferrite material thereby producing a low reflection coefficient, while frequencies above the cut-off are transmitted with very little attenuation. One of the conductors of the transmission system can further have microwave circuit elements located thereon which provide a second "filter" characteristic, such as a reactive filter or a tunnel diode. The filter characteristics produced by the ferrite material and the circuit elements combine to produce a desired system filter characteristic.

摘要： A wide-band ferrite limiter for operation in the microwave frequency rangeomprised of a plurality of intercoupled dielectric resonators having a long, thin ferrite rod passing through the longitudinal central axis of the dielectric resonant structure. Broadband operation is achieved by the proximity coupling of the dielectric resonators while the ferrite rod provides an optimized ferrite geometry which serves to increase the dynamic range and also to decrease the critical threshold field. A DC field of magnetization is additionally provided along the longitudinal central axis which with the availability of light-weight small rare earth magnets allows the limiter to be magnetized in such a fashion that a very compact device is achieved thereby.

摘要： This disclosure involves one or a plurality of cascaded YIG or similar magneto-elastic media propagating elastic waves transduced from a band of electromagnetic waves and having special magnetic field curved profiles and variable bias magnetic fields applied thereto such as to couple out or absorb the energy of specified variable frequencies to-be-filtered, by effecting conversions of the elastic waves of such specified frequencies only to spin waves. Cascaded units enable a bandpass characteristic to be produced that may be varied in width and center frequency.

摘要： In a low pass RF filter, a coating of barium titanate is applied to a ferrite substrate. In one embodiment, the RF filter is an extruded tube of ferrite coated with barium titanate. The tube is used as an RF filter for a connector pin. In another embodiment, a thin strip of ferrite is coated with barium titanate. This forms a filter strip for use on circuit boards or for use as a high capacity lossy power bus.

摘要： Electric field controllable devices which operate on the principle of velocity change of a wave passing therethrough. These waves can be magneto-elastic or spin waves, including surface waves. The materials used in these devices include Ga2 xFexO3, Cr2O3, and YIG. When the electric field across the device is changed, the cyclotron resonance frequency of the device is greatly shifted, resulting in wave velocity changes up to about 50 percent. A bias magnetic field is generally applied across the devices to establish a resonance frequency. Devices include variable delays, modulators, frequency translators, wave guides, tunable filters, etc.

摘要： Apparatus for providing time delay, frequency selectivity and/or switching of electromagnetic wave energy, that includes, a single- or multilayer magnetic material adapted, when magnetized, to convert electromagnetic wave energy in air, for example, to spin wave energy in the material, the electromagnetic wave energy being subjected to an abrupt discontinuity in the equilibrium environmental parameters to effect such conversion. The electromagnetic wave is converted within the material to a combination of evanescent and propagating spin waves. By controlling the abruptness of said discontinuity, it is possible, as discussed herein, to control the rate of decay ( Alpha ) of the evanescent wave and the wave number (k) of the spin wave thereby to control the rate of conversion and determine, further, the wavenumber of the spin wave. It has been found, for present purposes, that when Alpha k, the group velocity of the spin wave is minimum, thus making possible the use of thin films to provide substantial delay. There is also described apparatus and method in which the power within the material can be directed at some angle to the direction of the incoming wave to provide some time delay but, more importantly, to provide switching and/or filtration of an input signal; the latter apparatus and method do not ordinarily relate to thin film although thin film may be used. Further, operation is generally in the region of Alpha >>k.
