Abstract
After a discussion of various types of linear electromagnetic media, a general expression for the energy density for a lossless medium is derived by evaluation of the total influx of energy to a volume element. The result reduces to the commonly used expression only if the medium is nondispersive. The physical significance of the extra energy term resulting from the dispersion is discussed, and a general expression for the stored energy of an electric network is given.
