摘要： A tunable filter element comprises a resonator unit that defines a longitudinal axis, the resonator unit includes an inner conducting portion defining an inner shorting end along the longitudinal axis and an inner capacitive end opposing the inner shorting end, an outer conducting portion arranged around the inner conductor defining an outer shorting end along the longitudinal axis and an outer capacitive end opposite to the outer shorting end. The inner and the outer conductors maintain an annular gap there-between, and are coupled to form a shorting end at one end and a capacitive end at the other. The filter element further comprises a ferrite insert disposed between the inner and the outer conducting portions and substantially filling the annular gap, the ferrite insert being configured to receive a bias magnetic field in a direction substantially parallel to the longitudinal axis.

摘要： A coupled YIG resonator device for filtering a wide band microwave signal to provide a comparatively narrow output passband. The device has an enhanced bandwidth and improved out-of-band rejection relative to a single resonator configuration. The coupled resonator device includes a plurality of YIG films sharing a common non-magnetic substrate arranged in a plane and having a gap separating adjacent films. A dielectric layer has a first surface in contact with the YIG films and a second surface where a metallic ground plane is deposited. A magnetic biasing field is applied to the plurality of YIG films such that each forms a resonator having a resonance frequency. Adjacent resonators are magnetically coupled to each other by rf linkage across the gap therebetween. The magnetic coupling causes the respective resonance frequencies of the respective resonators to move apart relative to respective resonance frequencies occurring when no coupling is present, thereby enhancing the bandwidth and improving the out-of-hand rejection of the coupled resonator circuit. The center frequency of respective resonator circuits may be tuned by prescribing differing dimensions of the respective resonator circuits and applying a uniform magnetic biasing field. A microwave channelizer is comprised of a plurality of the aforementioned coupled YIG resonators integrated into one device. The channelizer separates microwave signals of different frequencies into individual output channels.

摘要： A band-pass filter includes a photonic crystal having a local mode that generates a pass band in a stop band formed by Bragg reflection, a transmission channel that limits electromagnetic waves propagating in the photonic crystal to a mode in which an amplitude direction of an electrical field is a particular direction; and a magnetic field-applying unit for applying to the photonic crystal a DC magnetic field in a direction perpendicular to a propagation direction of the electromagnetic waves. The photonic crystal includes a periodic structure including a low permittivity dielectric member and a plurality of high permittivity dielectric members periodically arranged in the low permittivity dielectric member so that the Bragg reflection occurs in the periodic structure, and a magnetic member disposed in the periodic structure.

摘要： A cylindrical cavity is loaded with a ferroelectric rod and is resonant at the dominant mode. The loaded cylidrical cavity is a band pass filter. As a bias voltage is applied across the ferroelectric rod, its permittivity changes resulting in a new resonant frequency for the loaded cylindrical cavity. The ferroelectric rod is operated at a temperature slightly above its Curie temperature. The loaded cylindrical cavity is kept at a constant designed temperature. The cylindrical cavity is made of conductors, a single crystal high Tc superconductor including YBCO and a single crystal dielectric, including sapphire and lanthanum aluminate, the interior conducting surfaces of which are deposited with a film of a single crystal high Tc superconductor. Embodiments also include waveguide single and multiple cavity type tunable filters. Embodiments also include tunable band reject filters.

摘要： A tunable bandpass filter comprising a pair of slot line resonant cavities formed in a metallic film covering the planar surface of a ferrite substrate. A magnetic biasing field of variable magnitude is generated and applied through the ferrite substrate transversely across the slot line resonant cavities. The magnetic field operates to change the electrical length of the resonant cavities due to the fact that the magnetic permeability of the ferrite material changes with the applied field.
