electrical engineering, dispersion relations describe the effect of dispersion on the properties of waves in a medium. A dispersion relation relates the wavelength...

relationship: the frequency dispersion relation ω 2 = Ω 2 ( k ) . {\displaystyle \omega ^{2}=\Omega ^{2}(k).\,} The dispersion relation has two solutions: ω = +Ω(k)...

In physics, the energy–momentum relation, or relativistic dispersion relation, is the relativistic equation relating total energy (which is also called...

wavelength: Dispersion (optics), for light waves Dispersion (water waves), for water waves Acoustic dispersion, for sound waves Dispersion relation, the mathematical...

result from coalescence of smaller wind-caused ripple-waves. The dispersion relation describes the relationship between wavelength and frequency in waves...

transverse optical phonons, this is due to the particular form of the dispersion relation of the phonon and photon and their interaction. Photons consist of...

DOS as a function of the wave vector, the system-specific energy dispersion relation between E and k must be known. In general, the topological properties...

of the acoustic dispersion relation, ∂ωk/∂k (see group velocity.) At low values of k (i.e. long wavelengths), the dispersion relation is almost linear...

the dispersion relation (relation between frequency and wavevector) is the same as in free space. At a higher frequency, the dispersion relation bends...

identical, as both are examples of a massless Bose gas with a linear dispersion relation. For a cube of side-length L {\displaystyle L} , the resonating modes...
