... permeability µrel may depend on the wave’s frequency, so n = κµrel and hence wave speed c/n may change with frequency. This is known as dispersion. For example, at low frequencies, water has a very large dielectric constant κ ≈ 80, which leads to n ≈ 9 and hence rather slow wave speed v = 0.11 c. Bu ...

... Sufficiently away from the source, the last term dominates. If it was the only term present, then the temporal dependence of the field would look like a somewhat distorted (differentiated) but otherwise just a shifted-in-time and reduced-in-magnitude copy of the current.
