  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. 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 ...

  4. Codes for electromagnetic scattering by spheres - Wikipedia

    en.wikipedia.org/wiki/Codes_for_electromagnetic...

    This program calculates the scattering, absorption, and attenuation parameters, as well as the angular scattering patterns of a single coated sphere according to Aden-Kerker theory. 2007 L. Liu, H. Wang, B. Yu, Y. Xu, J. Shen [15] C: Unknown Light scattering by a coated sphere (extinction efficiency, scattering efficiency, light scattering ...

  5. Insertion loss - Wikipedia

    en.wikipedia.org/wiki/Insertion_loss

    Here is one of the scattering parameters. Insertion loss is the extra loss produced by the introduction of the DUT between the 2 reference planes of the measurement. The extra loss can be introduced by intrinsic loss in the DUT and/or mismatch. In case of extra loss the insertion loss is defined to be positive.

  6. Light scattering by particles - Wikipedia

    en.wikipedia.org/wiki/Light_scattering_by_particles

    Scattering from any spherical particles with arbitrary size parameter is explained by the Mie theory. Mie theory, also called Lorenz-Mie theory or Lorenz-Mie-Debye theory, is a complete analytical solution of Maxwell's equations for the scattering of electromagnetic radiation by spherical particles (Bohren and Huffman, 1998).

  7. Radiative transfer equation and diffusion theory for photon ...

    en.wikipedia.org/wiki/Radiative_transfer...

    The RTE is a differential equation describing radiance (, ^,).It can be derived via conservation of energy.Briefly, the RTE states that a beam of light loses energy through divergence and extinction (including both absorption and scattering away from the beam) and gains energy from light sources in the medium and scattering directed towards the beam.

  8. Perfectly matched layer - Wikipedia

    en.wikipedia.org/wiki/Perfectly_matched_layer

    PML is widely used and has become the absorbing boundary technique of choice in much of computational electromagnetism. [1] Although it works well in most cases, there are a few important cases in which it breaks down, suffering from unavoidable reflections or even exponential growth.

  9. S-matrix - Wikipedia

    en.wikipedia.org/wiki/S-matrix

    In scattering theory, the S-matrix is an operator mapping free particle in-states to free particle out-states (scattering channels) in the Heisenberg picture. This is very useful because often we cannot describe the interaction (at least, not the most interesting ones) exactly.
