A bound on the group velocity for Bloch wave packets
journal contribution
posted on 2023-06-08, 19:01 authored by Grégoire Allaire, Mariapia Palombaro, Jeffrey RauchWe give a direct proof that the group velocities of Bloch wave packet solutions of periodic second order wave equations cannot exceed the maximal speed of propagation of the periodic wave equation.
