The skin depth is one of the most fundamental issues in microwave engineering, but it also affects lower frequencies,
even 60 cycle AC power. The skin depth equation is as relevant to microwave engineering as Newton's law (F=mA) is to physics.
Skin depth equationThe well-known equation for the skin depth is given below. Note that skin depth (δ) is a function of only three variables, frequency (f ), resistivity (ρ), and relative permeability (μr).
