  2. Capacitive coupling - Wikipedia

    en.wikipedia.org/wiki/Capacitive_coupling

    Capacitive coupling is the transfer of energy within an electrical network or between distant networks by means of displacement current between circuit(s) nodes, induced by the electric field. This coupling can have an intentional or accidental effect. Capacitive coupling from high-voltage power lines can light a lamp continuously at low intensity.

  3. Coupling coefficient of resonators - Wikipedia

    en.wikipedia.org/wiki/Coupling_coefficient_of...

    The coupling coefficient for the case of two equal resonators is defined by formula. (1) where are the frequencies of even and odd coupled oscillations of unloaded pair of the resonators and It is obvious that the coupling coefficient defined by formula (2) is a positive constant that characterizes interaction of resonators at the resonant ...

  4. Fano resonance - Wikipedia

    en.wikipedia.org/wiki/Fano_resonance

    Fano resonance. Plot of scattering cross-section versus normalized energy for various values of the parameter q illustrating the asymmetric Fano line-shape. In physics, a Fano resonance is a type of resonant scattering phenomenon that gives rise to an asymmetric line-shape. Interference between a background and a resonant scattering process ...

  5. Resonant inductive coupling - Wikipedia

    en.wikipedia.org/wiki/Resonant_inductive_coupling

    Resonant inductive coupling or magnetic phase synchronous coupling [4] [5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.

  6. Leakage inductance - Wikipedia

    en.wikipedia.org/wiki/Leakage_inductance

    Fig. 1 L P σ and L S σ are primary and secondary leakage inductances expressed in terms of inductive coupling coefficient under open-circuited conditions. The magnetic circuit's flux that does not interlink both windings is the leakage flux corresponding to primary leakage inductance L P σ and secondary leakage inductance L S σ .

  7. Charge trap flash - Wikipedia

    en.wikipedia.org/wiki/Charge_trap_flash

    Charge trap flash ( CTF) is a semiconductor memory technology used in creating non-volatile NOR and NAND flash memory. It is a type of floating-gate MOSFET memory technology, but differs from the conventional floating-gate technology in that it uses a silicon nitride film to store electrons rather than the doped polycrystalline silicon typical ...

  8. Coupling reaction - Wikipedia

    en.wikipedia.org/wiki/Coupling_reaction

    Coupling reaction. In organic chemistry, a coupling reaction is a type of reaction in which two reactant molecules are bonded together. Such reactions often require the aid of a metal catalyst. In one important reaction type, a main group organometallic compound of the type R-M (where R = organic group, M = main group centre metal atom) reacts ...

  9. J-coupling - Wikipedia

    en.wikipedia.org/wiki/J-coupling

    The full form of the J-coupling interaction between spins 'I j and I k on the same molecule is: H = 2π I j · J jk · I k. where J jk is the J-coupling tensor, a real 3 × 3 matrix. It depends on molecular orientation, but in an isotropic liquid it reduces to a number, the so-called scalar coupling. In 1D NMR, the scalar coupling leads to ...
