Skin depth is a measure of how deeply electromagnetic waves penetrate into a conductor before they are significantly attenuated. It is inversely proportional to the square root of frequency, conductivity, and magnetic permeability, meaning higher frequencies or more conductive materials result in shallower skin depths.

Electromagnetic waves are oscillations of electric and magnetic fields that travel through space at the speed of light, encompassing a broad spectrum from radio waves to gamma rays. They do not require a medium to propagate and are fundamental to many technologies, including communication, imaging, and energy transfer.

Conductivity is a measure of a material's ability to conduct electric current or heat, often quantified in terms of electrical conductivity or thermal conductivity. It is influenced by the material's structure, temperature, and the presence of impurities or defects.

Magnetic permeability is a fundamental property that quantifies how a material responds to a magnetic field, impacting how magnetic lines of force are distributed within the material. It is crucial in determining the inductance and magnetic behavior of components in electrical and electronic systems, influencing the design of transformers, inductors, and magnetic shielding.
