  2. Scattering parameters - Wikipedia

    en.wikipedia.org/wiki/Scattering_parameters

    Note the format of the parameter notation SXYab, where "S" stands for scattering parameter or S-parameter, "X" is the response mode (differential or common), "Y" is the stimulus mode (differential or common), "a" is the response (output) port and b is the stimulus (input) port. This is the typical nomenclature for scattering parameters.

  3. T-matrix method - Wikipedia

    en.wikipedia.org/wiki/T-matrix_method

    The standard way to calculate the T-matrix is the null-field method, which relies on the Stratton–Chu equations. [6] They basically state that the electromagnetic fields outside a given volume can be expressed as integrals over the surface enclosing the volume involving only the tangential components of the fields on the surface.

  4. Nicolson–Ross–Weir method - Wikipedia

    en.wikipedia.org/wiki/Nicolson–Ross–Weir_method

    The method uses scattering parameters of a material sample embedded in a waveguide, namely and , to calculate permittivity and permeability data. and correspond to the cumulative reflection and transmission coefficient of the sample that are referenced to the each sample end, respectively: these parameters account for the multiple internal reflections inside the sample, which is considered to ...

  5. S-matrix - Wikipedia

    en.wikipedia.org/wiki/S-matrix

    The S-matrix is closely related to the transition probability amplitude in quantum mechanics and to cross sections of various interactions; the elements (individual numerical entries) in the S-matrix are known as scattering amplitudes. Poles of the S-matrix in the complex-energy plane are identified with bound states, virtual states or resonances.

  6. Lippmann–Schwinger equation - Wikipedia

    en.wikipedia.org/wiki/Lippmann–Schwinger_equation

    It relates the scattered wave function with the interaction that produces the scattering (the scattering potential) and therefore allows calculation of the relevant experimental parameters (scattering amplitude and cross sections). The most fundamental equation to describe any quantum phenomenon, including scattering, is the Schrödinger equation.

    England opted against making any changes in personnel for the visit of Australia on Saturday after being edged by New Zealand last weekend. A 24-22 defeat by the All Blacks opened England's autumn ...

  9. Electron scattering - Wikipedia

    en.wikipedia.org/wiki/Electron_scattering

    Single scattering: when an electron is scattered just once. Plural scattering: when electron(s) scatter several times. Multiple scattering: when electron(s) scatter many times over. The likelihood of an electron scattering and the degree of the scattering is a probability function of the specimen thickness and the mean free path. [6]
