  • This formula applies to slight conductors.

  •  Equal to the inverse of the complex component of the wave number, ki.

  •  Relative permittivity = dielectric constant.

  • Equals the distance over which an incident wave decays to 1/e it's initial amplitude.

  •  A conductor is "slight" when:
