Definition

Frequency‑dependent redistribution of alternating current density toward the outer surface of a conductor, causing an effective increase in resistance at higher frequencies; characterized by the skin depth δ = sqrt(2/ωμσ) in homogeneous, linear media (ω angular frequency, μ permeability, σ conductivity).
