    摘要: Disclosed herein is a nonreciprocal circuit element that includes a magnetic rotator disposed between first and second ground conductors, and a permanent magnet that applies a DC magnetic field to the magnetic rotator. The magnetic rotator includes a first ferrite core having a first surface covered with the first ground conductor, a second ferrite core having a second surface covered with the second ground conductor, a first center conductor directly fixed to a third surface of the first ferrite core positioned opposite to the first surface, and a second center conductor directly fixed to a fourth surface of the second ferrite core positioned opposite to the second surface.

    摘要: [Problem] When a nonreciprocal device operating at 100 GHz to 300 GHz is to be realized by using a conventional magnetic material of garnet-type ferrite or spinel-type ferrite, a huge permanent magnet is required and, therefore, it is very difficult to achieve a millimeter-wave band nonreciprocal device for practical use.[Solving means] To solve this problem, there is provided a millimeter-wave band nonreciprocal device composed of a magnetic material represented by a formula ε-MxFe2-xO3 (0

    摘要: A non-reciprocal component element for integrated optics characterized by a substrate having a pair of waveguides disposed thereon either in a stacked relationship or a closely spaced side-by-side relationship with one of the pair of waveguides being of a magneto-optic material having an index of refraction greater than the index of refraction of the substrate. The component has a magnetic field extending in the plane of the waveguides and perpendicular to the direction of propagation of the waves therein. The component is preferably provided with a pair of 3dB couplers and in one embodiment, the magnetic field is controllable so that the element acts as a modulator.

    摘要: A central conductor assembly for use in a non-reciprocal circuit comprising a first inductance element between a first input/output port and a second input/output port, and a second inductance element between the second input/output port and a ground port, a magnetic substrate being integrally provided with a first central conductor constituting the first inductance element and a second central conductor constituting the second inductance element; and the second central conductor being crossing the first central conductor on a main surface side of the substrate via a magnetic layer or a dielectric layer, with at least one end portion thereof bent such that high-frequency current flows therethrough in the same direction as or in an opposite direction to that of high-frequency current flowing through the first central conductor.
