  2. Coaxial cable - Wikipedia

    en.wikipedia.org/wiki/Coaxial_cable

    Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

  3. Coaxial - Wikipedia

    en.wikipedia.org/wiki/Coaxial

    In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis. The two-dimensional analog is concentric. Common examples: A coaxial cable has a wire conductor in the centre (D), a circumferential outer conductor (B), and an insulating medium called the dielectric (C) separating these two conductors. The ...

  4. Skin effect - Wikipedia

    en.wikipedia.org/wiki/Skin_effect

    Refer to the diagram below showing the inner and outer conductors of a coaxial cable. Since skin effect causes a current at high frequencies to flow mainly at the surface of a conductor, it can be seen that this will reduce the magnetic field inside the wire, that is, beneath the depth at which the bulk of the current flows.

  5. Transmission line - Wikipedia

    en.wikipedia.org/wiki/Transmission_line

    One of the most common types of transmission line, coaxial cable. In electrical engineering, a transmission line is a specialized cable or other structure designed to conduct electromagnetic waves in a contained manner. The term applies when the conductors are long enough that the wave nature of the

  6. Unbalanced line - Wikipedia

    en.wikipedia.org/wiki/Unbalanced_line

    A coaxial line (coax) has a central signal conductor surrounded by a cylindrical shielding conductor. The shield conductor is normally grounded. The coaxial format was developed during World War II for use in radar. It was originally constructed from rigid copper pipes, but the usual form today is a flexible cable with a braided screen.

  7. Shielded cable - Wikipedia

    en.wikipedia.org/wiki/Shielded_cable

    Four-conductor shielded cable with metal foil shield and drain wire. Coaxial cable. Electronic symbol for a shielded wire. A shielded cable or screened cable is an electrical cable that has a common conductive layer around its conductors for electromagnetic shielding. [1] This shield is usually covered by an outermost layer of the cable.
