摘要： Filter arrangement comprising an inner electric conductor comprising at least one inner conductor segment, an outer electric conductor at least partly surrounding the inner conductor, at least one dielectric element and at least one coil spring. The at least one dielectric element is arranged sandwiched between at least one inner conductor segment and the outer conductor to form a capacitance between the outer conductor and the inner conductor segment. The at least one coil spring is arranged inside said outer conductor to force the inner conductor segment and the at least one dielectric element against the outer conductor. The at least one coil spring is made from an electrically conducting material to form an inductance and is electrically connected with the inner conductor segment.

摘要： A feeding structure is provided that includes a reference electrode, first and second substrates opposite to each other, and a dielectric layer between the first and second substrates. The first substrate includes a first base plate and an input electrode on a side of the first base plate proximal to the dielectric layer. The second substrate includes a second base plate and a receiving electrode on a side of the second base plate proximal to the dielectric layer, and orthographic projections of the receiving electrode and the input electrode on the first base plate at least partially overlaps each other to form a coupling structure. An output terminal of the input electrode or the receiving electrode is connected to a phase shifting structure to differ a phase of a microwave signal transmitted via the first substrate from a phase of a microwave signal transmitted via the second substrate.

摘要： The present disclosure relates to a metasurface arrangement including a first metasurface and a second metasurface which run mutually parallel and face each other. Each metasurface includes a corresponding periodic or quasi-periodic structure formed in a respective pattern. The first metasurface is formed in a dielectric material structure and the second metasurface is formed in either a dielectric material structure or in an electrically conducting structure. The periodic or quasi-periodic structure on the first metasurface is configured to yield a first response to an incident electromagnetic wave between the two metasurfaces, and the periodic or quasi-periodic structure on the second metasurface is configured to yield a second response to the incident electromagnetic wave between the two metasurfaces that is equivalent to the first response, thereby rendering the two metasurfaces mutually electromagnetically symmetric.

摘要： An architecture for, and techniques for fabricating, a thermal decoupling device are provided. In some embodiments, thermal decoupling device can be included in a thermally decoupled cryogenic microwave filter. In some embodiments, the thermal decoupling device can comprise a dielectric material and a conductive line. The dielectric material can comprise a first channel that is separated from a second channel by a wall of the dielectric material. The conductive line can comprise a first segment and a second segment that are separated by the wall. The wall can facilitate propagation of a microwave signal between the first segment and the second segment and can reduce heat flow between the first segment and the second segment of the conductive line.
