The Deep Physical Mechanisms of Resonance Absorption Phenomena: A Theoretical Exploration in Multilayer Metallic Metamaterials

This paper establishes a classification system for resonance absorption mechanisms in multilayer metallic metamaterials, categorizing absorption into Scattering Absorption, Optical Path Absorption, and Localized Field Absorption. The system reveals the energy pathways, dissipation processes, and localized losses during the metamaterial absorbers' response to electromagnetic waves. It provides a theoretical foundation for optimizing metamaterial absorbers and offers a new perspective on resonance absorption phenomena.
