Why is high energy storage density important?
High energy storage density is required for the need of devices’ miniaturization and lightweight, since more energy can be stored when the volume is the same. An ideal energy storage dielectric should have large dielectric constant and high breakdown strength at the same time.
Do nanogratings have local energy storage and power dissipation density?

Do nanostructures have electromagnetic energy storage and power dissipation?

How does energy density affect energy storage?
For energy storage, the energy density relates the stored energy to the volume of the storage equipment, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy.
What is energy density?
Energy density differs from energy conversion efficiency (net output per input) or embodied energy (the energy output costs to provide, as harvesting, refining, distributing, and dealing with pollution all use energy). Large scale, intensive energy use impacts and is impacted by climate, waste storage, and environmental consequences.
Do materials optical properties affect energy storage and power dissipation density?
The optical property of materials has been studied by many researchers in relation to energy storage and power dissipation density. Early works on this topic were conducted by Loudon, Barash, Ginzburg, Brillouin, and Landau, among others. More recent studies have been carried out by Ruppin, Shin et al., and Vorobyev.
