In the physical sciences and electrical engineering, dispersion relations describe the effect of dispersion on the properties of waves in a medium. A dispersion relation relates the wavelength or wavenumber of a wave to its frequency. Given the dispersion relation, one can calculate the phase velocity and … See more Plane waves in vacuum are the simplest case of wave propagation: no geometric constraint, no interaction with a transmitting medium. Electromagnetic waves in a vacuum For See more Isaac Newton studied refraction in prisms but failed to recognize the material dependence of the dispersion relation, dismissing the work … See more As mentioned above, when the focus in a medium is on refraction rather than absorption—that is, on the real part of the refractive index—it is common to refer to the functional dependence of angular frequency on wavenumber as the dispersion relation. … See more • Ellipsometry • Ultrashort pulse See more • Poster on CBED simulations to help visualize dispersion surfaces, by Andrey Chuvilin and Ute Kaiser • Angular frequency calculator See more WebMay 2, 2024 · The dispersion relationship is $\omega = f(k)$ where $f$ is some funciton, $\omega$ the angular frequency, and $k$ the momentum.
