Özet

This chapter discusses the emergence conditions of energy states arisenfrom the interaction of electromagnetic waves with an optically active planar slab cov-ered by graphene sheets. All energy configurations inside and outside the graphenelayers are explicitly revealed. In particular, we specialize to some certain cases ofmaximal energy storage by imposing the spectral singularity condition, and showthat energy density stored within graphene layers can be increased tremendouslybecause of the presence of graphene layers surrounding the complex potential slab.Method presented here relies on the most fundamental principles embracing itspower from Maxwell’s equations and employing the whole control of transfer matrixformalism of scattering theory. In this respect, various situations are discussed to seehow graphene sheets can be handled in order to increase the energy storage within aslab. It is attained that both graphene layers are required and there must be currentsflowing in the same direction in order to preserve the parity invariance. If the parityinvariance is broken, energy stored inside the slab slumps to much lower values.Besides, it is illustrated that graphene features can be effectively used in order toenhance energy storage efficiently. Predictions proposed in this work are perceptiblysupported by the corresponding graphical demonstrations. The suggested method isquite illustrative and instructive, and give rise to extend all other cases by followingsimilar steps. These observations and predictions suggest a concrete and sound wayof forming graphene-related energy storage devices
