I am studying phase and group velocity in non-dispersive and dispersive media. My question is the following: Is there any reason why a dispersive medium simply cannot be modeled as a type of field?

A dispersive medium is any material or substance that causes light or other electromagnetic waves to travel at different speeds depending on the wavelength or frequency of the wave. This results in the separation of white light into its component colors.
A dispersive medium causes light to refract or bend as it travels through the material, with each wavelength bending at a different angle. This leads to the separation of colors and the formation of a spectrum.
Common examples of dispersive mediums include glass, water, and prisms. Air can also act as a dispersive medium, causing atmospheric refraction of light.
The dispersion of light can lead to chromatic aberration, where different wavelengths of light focus at different points, resulting in blurred or distorted images. This effect can be minimized by using corrective lenses or coatings.
Dispersive mediums are commonly used in technologies such as spectrophotometers, which use the separation of colors to analyze the composition of substances. They are also used in optical communications and fiber optics to transmit data using different wavelengths of light.
