On the Fundamental Limitations of Artificial Magnetic Materials

In order to study the functionality of physical and geometrical properties of inclusions in engineered magnetic materials, a novel model is developed which integrates all parameters in two geometrical and physical indices. To generalize this framework for any type of applications, all frequencies are normalized to the operational frequency. Based on this model, a geometry invariant fundamental constraint is derived. This constraint provides the operational bandwidth restriction based on the amount of permissible variation of the effective permeability.
