"WebbBloch analysis was originally developed to solve Schrodinger’s equation for the electron wave function in a periodic potential field, such as found in a pristine crystalline solid. In the context of Schrodinger’s equation, damping is absent and energy is conserved. More recently, Bloch analysis has found application in periodic macroscale materials, such as … " - Theory of damped bloch waves in elastic media
