This is equivalent to the effective permeability formulation proposed by Klinkenberg:
2.
It is the ratio of the effective permeability of that phase to the absolute permeability.
3.
The experimental results showed that the flow of a mixture experienced an effective permeability that was reduced compared to the single-phase permeability.
4.
Effective permeability " ?eff " is boosted from the inductance of the rings and the capacitance occurs at the gaps of the split rings.
5.
In multiphase flow in porous media, the "'relative permeability "'of a phase is a dimensionless measure of the effective permeability of that phase.
6.
As effective media, metamaterials can be characterized with complex ? ( w ) = ? 1 + i? 2 for effective permittivity and ?( w ) = ?1 + i ?2 for effective permeability.
