6. Conclusion

In this chapter, on the base of two basic systems of Maxwell's Eqs. (1–4) and

! ! (5–8) for electromagnetic field vectors E and B in a uniformly rotating dielectric medium, the two corresponding systems of wave Eqs. (67, 68) and (69, 70) have been derived (to the first order in Ω).

From their comparative analysis, it can be seen that the structure of the wave equations for electromagnetic field vectors in system (67, 68) is asymmetrical with respect to Ω, while the structure of such equations for these vectors in system (69, 70) is symmetrical.

On this basis, it can be concluded that if the principle of symmetry is accepted as a criterion for selection, then system of wave Eqs. (69, 70) for electromagnetic field ! ! vectors E and B may be preferred. The same conclusion may be also made about the original system of Maxwell's Eqs. (5–8) on the base of which set of wave Eqs. (69, 70) has been obtained.
