Wave dispersion that occurs without energy loss is examined and media capable of supporting waves with such dispersion are developed. The media are homogeneous and dispersive. The dispersion of the waves they generate shares many of the characteristics of the dispersion of waves propagating through inhomogeneities. Thus these media can be useful in modeling the propagation of waves in inhomogeneous media. An example supporting the utility of modeling applications is presented.
