摘要： A microwave resonator device including a first resonator member comprised of a dielectric material and a second resonator member comprised of a dielectric material. The second resonator member can be positioned spatially offset from the first resonator member to define a spatial interaction region configured to confine an electromagnetic field in a microwave region of the electromagnetic spectrum. The spatial offset between the first resonator member and the second resonator member defining the spatial interaction region is less than the microwave wavelength associated with a resonant frequency of the microwave resonator device. The microwave resonator device facilitates generation of a resonant field enhancement within the spatial interaction region.

摘要： A superconducting input and/or output system employs at least one microwave superconducting resonator. The microwave superconducting resonator(s) may be communicatively coupled to a microwave transmission line. Each microwave superconducting resonator may include a first and a second DC SQUID, in series with one another and with an inductance (e.g., inductor), and a capacitance in parallel with the first and second DC SQUIDs and inductance. Respective inductive interfaces are operable to apply flux bias to control the DC SQUIDs. The second DC SQUID may be coupled to a Quantum Flux Parametron (QFP), for example as a final element in a shift register. A superconducting parallel plate capacitor structure and method of fabricating such are also taught.

摘要： An electromechanical motor (1) comprises a stator (2) and a translator (10). The stator has two electromechanical actuators (20) having electromechanically active material (26) and means (35) for providing exciting signals. The translator is arranged between, and in driving contact with, driving portions (22) of the electromechanical actuators. The stator has a spring element (30) arranged for holding the driving portions against the translator. The electromechanical actuators are arranged for providing a vibration, which gives rise to a driving action, directed in a driving direction (X) perpendicular to the direction of the normal force, against the surface of the translator. The electromechanical motor further comprises a guiding means (50) having a circular hole (52). The translator has a cylindrically shaped guidance part (16) arranged at least partly in the circular hole. A tunable high-frequency filter comprising such a motor is also disclosed.

摘要： A balanced-type strip-shaped dielectric substrate integrated filter includes: a high-k dielectric substrate; and first low-k dielectric substrates, second low-k dielectric substrates and metal grounds are symmetrically stacked on upper and lower surfaces of the high-k dielectric substrate. Compared with an existing balanced-type dielectric filter, a high Q-value strip-shaped dielectric substrate integrated resonator with a packageable characteristic which works in TM111 mode and employs strip-shaped dielectric blocks with double grooves, combined with air groove structures of upper and lower layers and a packaging substrate is proposed, so that problems that cost is high and self-packaging cannot be realized of the existing balanced-type dielectric filter when being implemented by combining ceramic dielectric with a metal chamber structure can be solved, and thereby a balanced-type strip-shaped dielectric substrate integrated filter with the characteristic of low loss is realized; and meanwhile the filter may have advantages of self-packaging, high integration level and low cost.
