Extended phenomenological electrodynamics of dye-solvent mixture

In the paper, the description of dynamics of the electromagnetic fields in dye-solvent mixture in the concept of extended phenomenological electrodynamics is presented. For the description of the structure of material, a phenomenological model of the multi-component body is used. Such a model is based on the following assumptions: 1) a body consists of many homogeneously (ideally mixed) different components and 2) all components are located in each space point occupied by the body. It seems that the dye-solvent mixture fulfils the above phenomenological supposition for the multi-component body. Dynamics of the electromagnetic field has been expressed in the Lagrange-Hamiltonian formalism, and can be used in investigation of the local electromagnetic field in dye-solvent mixture.
