Are there any equations for these? I have seen in books for the vacuum case but not for a dispersive media.

Retarded potentials refer to the electromagnetic field that is generated by a moving charge in dispersive media. These potentials are considered "retarded" because they take into account the finite speed at which electromagnetic waves propagate through the medium.
Dispersive media, such as materials with varying refractive indices, can impact the propagation of electromagnetic waves, which in turn affects the behavior of retarded potentials. This can result in changes in the speed and direction of the potentials, as well as alterations in their amplitude and phase.
Understanding the behavior of retarded potentials in dispersive media is crucial for many applications in the fields of optics, telecommunications, and electromagnetics. It allows us to better predict and control the behavior of electromagnetic waves in different materials, leading to advancements in technologies such as optical fibers and lenses.
The calculation of retarded potentials in dispersive media involves solving Maxwell's equations, which describe the behavior of electromagnetic fields. This can be a complex mathematical process, but it can be simplified by using techniques such as perturbation theory and numerical simulations.
Dispersive media can be found in various forms, such as in transparent materials, biological tissues, and even the Earth's atmosphere. Some examples of how dispersive media affect retarded potentials include the bending of light in a prism, the dispersion of colors in a rainbow, and the refraction of light in the eye's lens.
