SUMMARY
The discussion clarifies the relationship between electric displacement field (D), electric field (E), and polarization (P) in different media. In a vacuum, where P equals zero, the electric field E is greater than in insulating mediums. However, in metamaterials, where polarization can oppose the electric field direction, this relationship can change, particularly for oscillating electromagnetic fields at specific frequencies. The constant nature of ∇D across mediums is also highlighted.
