SUMMARY
The permittivity matrix in anisotropic materials is definitively symmetric, as established through the analysis of the Poynting vector. This symmetry is essential for the proper definition of electromagnetic energy. Arguments supporting this symmetry often appear circular, but they are grounded in the fundamental principles of electromagnetism.
