Core Physics Concepts

Negative Refraction

n = ±√(ε·μ)

When both permittivity (ε) and permeability (μ) are negative simultaneously, the refractive index becomes negative, causing backward wave propagation.

Transformation Optics

ε' = Λ·ε·Λᵀ/det(Λ)

Coordinate transformations map to anisotropic material parameters, enabling arbitrary light bending for cloaking applications.

Drude-Lorentz Model

ε(ω) = 1 - ωₚ²/(ω² + iγω)

Effective medium models describe metamaterial electromagnetic response through plasma and resonance frequencies with damping.
