The dispersion relations (1.3) are written in the form of a system of algebraic equations for the coordinates of the vectors k, l, and ω and for an auxillary unknown variable d with the coeﬃcients depending on the period matrix τ. For m =1, 2, 3 for generic matrix τ one can solve the dispersion relations in the form k = k(τ),l= l(τ),ω = ω(τ) Now that we understand the dispersion relation for systems, it’s easy to understand the dispersion relation for the Schrodinger equation.

For instance, the dispersion relation of the Klein-Gordon equation is just (in units with ℏ and c = 1) ω 2 = k 2 + m 2 which just converts to the well-known relativistic equation E 2 = p 2 + m 2. Dispersion relations and ω–k plots Returning to our development, our original plane wave in equation [2] propagates in the most ordinary way with a phase speed equal to the free-space wave speed c s.

Con-versely, the analysis of transport measurements provides a great deal of information on E(~k). 2019-01-01 In this video I show how the dispersion relation and Schrodinger equation are important to eachother PSPs, is the dispersion relation. This relation is the basis for understanding of coupling of light to PSPs, by using special approaches to match the wavevector. Moreover, it can be used to predict the matching of localised surface plasmons (LSPs) and PSPs to achieve highly enhanced electromagnetic ﬁeld and/or tailored transmission. I believe for nonlinear PDE's the words dispersion relation refer to the behaviour of the plane wave solutions of the linearised form of the equation.
