# 11: Constitutive Parameters of Some Common Materials


• 11.1: Permittivity of Some Common Materials
The values below are relative permittivity for a few materials that are commonly encountered in electrical engineering applications, and for which permittivity emerges as a consideration. Note that “relative permittivity” is sometimes referred to as dielectric constant.
• 11.2: Permeability of Some Common Materials
The values below are relative permeability for a few materials that are commonly encountered in electrical engineering applications, and for which the relative permeability is significantly different from 1 . These materials are predominantly ferromagnetic metals and (in the case of ferrites) materials containing significant ferromagnetic metal content.
• 11.3: Conductivity of Some Common Materials
The values below are conductivity σ for a few materials that are commonly encountered in electrical engineering applications, and for which conductivity emerges as a consideration. Note that materials in some applications are described instead in terms of resistivity, which is simply the reciprocal of conductivity.
