Generalized Electromagnetic Energy Density in Time-Dependent Composite Media
The Lorentz medium model for magnetization is modification, through which the whole Lorentz models become more symmetric one than traditional forms used in [3-5]. The modification can also have the deduction for more general Poynting’ theorem in dispersive media became a regular procedure. As an application, those forms of energy density in [4, 5] are special cases of generalized one shown in the letter under the establishment conditions for time-independent situation.
