IEVref: 221-03-04 ID: Language: en Status: Standard Term: scalar permeability for circularly polarized fields Synonym1: Synonym2: Synonym3: Symbol: μ+, μ− Definition: of a material saturated by a magnetostatic field, the complex permeability when it is subjected to an electromagnetic wave having a circularly polarized $\stackrel{\to }{H}$ field component in the plane perpendicular to the magnetostatic field strength: μ+ = μr + κr μ− = μr − κr where μr and κr are components of Polder's tensor permeability NOTE – The subscript of µ corresponds to the sign in the mathematical expression; μ+ is applicable where the $\stackrel{\to }{H}$ field rotates counterclockwise as a function of time when seen in the direction of the applied magnetostatic field; μ− is applicable to the reverse rotation.
