摘要： A microwave frequency magnetic field manipulation system (10) comprises a re-entrant microwave cavity (12) having a substantially continuous and closed internal surface (14) with at least two opposite sides (16 and 18). Two or more posts, P1, P2, . . . Pn (hereinafter referred to in general as “posts P”) are provided in the cavity (12). The posts P are in physical and more particularly electrical contact with one of the sides 16. Respective gaps G atre or can be formed between free ends of the posts P and the side (18). The system (10) also has a signal source (20) coupled to the cavity (12) for supplying microwaves. The source (20) supplies microwave signals at frequencies that facilitate the generation of magnetic fields in opposite directions about at least two mutually adjacent posts P. Accordingly the magnetic field is reinforced in a common region (22) between the mutually adjacent posts P.

摘要： The present disclosure generally relates to a shielded patterned ground structure in a PCB. The PCB may be disposed in a hard disk drive. Conductive traces in PCBs can have the problem of common mode current flowing through the traces and thus increasing the magnitude of EMI noise. By providing a shielded patterned ground structure, the common mode current is reduced as is the magnitude of EMI noise, yet there is no negative impact to the differential signal.

摘要： The present application relates to a harmonic oscillator. The harmonic oscillator includes a dielectric body and at least one responding unit attached onto a surface of the dielectric body, where the responding unit is a conductive structure having a geometrical pattern. The application further relates to a cavity filter having the harmonic oscillator and an electromagnetic wave device. By using the harmonic oscillator in the application, a permittivity can be effectively increased and a resonance frequency of a cavity filter can be decreased, thereby implementing miniaturization. Moreover, for an electromagnetic wave in a TM mode, a frequency can be decreased and an electromagnetic loss is not affected.

摘要： A bandpass filter for microwave-frequency wave which is frequency tunable, comprises at least one resonator. Each resonator comprises a cavity having a conducting wall substantially cylindrical in relation to an axis Z, and at least one dielectric element disposed inside the cavity. The resonator resonates on two perpendicular polarizations having respectively distributions of the electromagnetic field in the cavity that are deduced from one another by a rotation of 90° and according to one and the same frequency. The wall of the cavity comprises an insert section facing the element having a different shape from a section not situated facing the element. The insert section and the element are able to perform a rotation with respect to one another in relation to the axis Z so as to define at least a first and a second relative position differing by an angle substantially equal to 45° to within 20°.

摘要： A technique relates to a superconducting airbridge on a structure. A first ground plane, resonator, and second ground plane are formed on a substrate. A first lift-off pattern is formed of a first lift-off resist and a first photoresist. The first photoresist is deposited on the first lift-off resist. A superconducting sacrificial layer is deposited while using the first lift-off pattern. The first lift-off pattern is removed. A cross-over lift-off pattern is formed of a second lift-off resist and a second photoresist. The second photoresist is deposited on the second lift-off resist. A cross-over superconducting material is deposited to be formed as the superconducting airbridge while using the cross-over lift-off pattern. The cross-over lift-off pattern is removed. The superconducting airbridge is formed to connect the first and second ground planes by removing the superconducting sacrificial layer underneath the cross-over superconducting material. The superconducting airbridge crosses over the resonator.
