Resumo
In the last decade, various works have demonstrated that a
class of artificial material called metamaterials (MTM) can
synthesize μ-negative (MNG) media capable of evanescentwave
focusing which largely enhances the magnetic
coupling between coils, which is the basic mechanism of
Inductive Power Transmission (IPT) systems. In the present
work, MTM-enhanced coupling in IPT systems is examined
through analytical and numerical results, which are
validated by experimental data. Adopting a transmissionline
based approach to describe the general MTM-enhanced
IPT system, it is evidenced that MNG MTMs can be
interpreted as a negative impedance from a circuital point of
view.
