Photon dispersion relation
WebThe dispersion relation 58 is plotted in the inset in Fig. 5. It exhibits an isotropic band gap centered about the frequency o /2. The lower and upper band-edge frequencies are v and c , respectively. WebThereafter, the dispersion may become nonlinear, either flattening or upturning, depending on the substance. Another very recent possibility to check the linear dispersion relation at terahertz frequencies is the simulation of model glasses with large periodicity volumes (a terahertz sound wave has a wavelength of 1 6 nm). These investigations ...

WebThis is in contrast to the electron propagation where we get the dispersion relation for anon-relativistic,massiveparticle(2.6). Instead, the dispersion relation for phonons is more reminiscent of the massless, relativistic dispersion relation for light.
