Abstract

The standard expressions for averaged energy density and energy flow of waves in dispersive media are generalized in order to include effects due to strong dispersion and/or broad band signals. A close relationship is revealed between these generalized energy expressions and the bilinear concomitants corresponding to the dispersion operator, which governs the wave motion.
