    摘要： A tunable frequency selective limiter is disclosed. In one or more embodiments, the tunable frequency selective limiter includes a first electrically conductive path (110). The tunable frequency selective limiter also includes a ferrimagnetic layer (120) disposed adjacent to the first electrically conductive path. The tunable frequency selective limiter further includes a second electrically conductive path (140) coiled around the first electrically conductive path and the ferrimagnetic layer. An electromagnetic current transmitting through the second electrically conductive path produces a magnetic field coupled to the ferrimagnetic layer. The tunable frequency selective limiter further includes a dielectric layer (130), wherein the ferrimagnetic layer is disposed on the dielectric layer. The portions of the second electrically conductive path that are at the interface of the dielectric layer and the ferrimagnetic layer may be embedded into the dielectric layer or may be disposed on the surface of the dielectric layer.

    摘要： The present disclosure is directed towards a frequency selective limiter having a first magnetic material (42) disposed over a first dielectric material (44) and a strip conductor (46,66) disposed over the magnetic material. In some embodiments, the frequency selective limiter includes a second magnetic material disposed over the strip conductor and a second dielectric material disposed over the second magnetic material. The first and second dielectric material may have a lower relative permittivity than the first and second magnetic material. In an embodiment, the frequency selective limiter includes a slow wave structure disposed to magnetically couple a magnetic field, produced by electromagnetic energy propagating through the slow wave structure, into the magnetic material.

    摘要： A non-linear transmission line device includes a magnetic element having at least one end profiled to reduce demagnetisation when the element is biased. The profile may be tapered, stepped, or smoothly curved. Also disclosed is a non-linear transmission device made up of a solid magnetic element, typically of flat rectangular form.
