Giant magnetoelectric field separation via anapole-type states in high-index dielectric structures
Giant magnetoelectric field separation via anapole-type states in high-index dielectric structures
Quality of spatial separation between electric and magnetic fields in an electromagnetic wave is fundamentally constrained by nonlocal nature of Maxwell equations. While electric and magnetic energy densities in a wave, propagating in vacuum, are equal at each point in space, carefully designed photonic structures can enable surpassing this limit. …
