pleclair.ua.eduNov 13, 2001 · term. In metals, the real part of the permittivity is usually equal to the permittivity of free space, and the imaginary part is usually zero. Semiconductors maintain a relative balance between the two terms. Thus, when an effective conductivity is specified on a data sheet, it is useful to remember that it arises from two sources.
