The nonreciprocal transmission line part has a propagation constant and an operating frequency set in a dispersion curve that represents a relation between the propagation constant and the operating frequency so that the propagation constant in the forward direction and the propagation constant in the backward direction have nonreciprocal phase characteristics different from each other.

  • Patent number: 8237516
    Abstract: In enhancing signal quality through packages, meta-materials may be used. Meta-materials are designed to make the signal act in such a way as to make the shape of the signal behave as though the permittivity and permeability are different than the real permittivity and permeability of the insulator used. In an example embodiment, a substrate (10) is configured as a meta-material. The meta-material provides noise protection for a signal line (15) having a pre-determined length disposed on the meta-material. The substrate comprises a dielectric material (2, 4, 6) having a topside surface and an underside surface. A conductive material (30) is arranged into pre-determined shapes (35) having a collective length. Dielectric material envelops the conductive material and the conductive material is disposed at a first predetermined distance (55) from the topside surface and at a second predetermined distance from the underside surface.

  • Publication number: 20110266888
    Abstract: A bipolar pulse generator includes two, two-conductor transmission lines coupled together with a load positioned between the two transmission lines. Each conductor of a transmission line we define as a segment. Two segments of one transmission line are charged and switchably coupled to two segments of the other transmission line to produce a bipolar pulse on the matched load. This bipolar pulse generator may be implemented in a flat or a folded design. The generator may include two transmission line structures coupled together with a load positioned between each transmission line structures. The first transmission line structure may include a stepped transmission line and an embedded transmission line segment. A switch may be coupled between the embedded transmission line segment and another segment of the transmission line structure.

    Abstract: The invention relates to a method and a device for pseudo-differential transmission through interconnections used for sending a plurality of electrical signals. An interconnection having 4 transmission conductors and a return conductor distinct from the reference conductor cannot be modeled as a uniform multiconductor transmission line. Each end of the interconnection is connected to a termination circuit. Three damping circuits are connected between the return conductor and the reference conductor. The transmitting circuits receive at their inputs the signals from the 4 channels of the two sources, and are connected to the interconnection. The receiving circuits are connected to the interconnection, each receiving circuit being such that the signals of the 4 channels of a source connected to a transmitting circuit in the activated state are sent to the four channels of the destinations, without noticeable echo, internal crosstalk and external crosstalk.

    Abstract: Provided is an electromagnetic wave transmission sheet having a mesh-shaped electrode. The sheet has a length of width in a direction vertical to the propagation direction of the transmitted electromagnetic wave which length is substantially identical to half of the wavelength of the transmitted electromagnetic wave multiplied by a natural number so that a resonance state is obtained in the vertical direction. It is preferable that the sheet have an electromagnetic wave absorbing medium for reducing reflection of the transmitted electromagnetic wave in the propagation direction, so as to eliminate the need of an electromagnetic wave absorbing medium for reducing reflection in the direction vertical to the propagation direction of the transmitted electromagnetic wave.
