摘要

Different approaches are reviewed to design conducting inclusions with specific microwave magnetic response. Several types of non-resonant and resonant inclusions are presented, and experimental measurements are reported. Inductive inclusions with a load made of electronic components are attractive to build sophisticated frequency response. They can be described by a simple model and a straightforward expression of the permeability as a function of the impedance of the load and the inductance of the inclusion has been derived. This model accounts for the experimental observations. The relative merits of conventional magnetic materials and artificial magnetic materials are compared through sum rules. It appears that at low frequencies, magnetic materials lead to much larger permeability levels, and combining inductive structures with a magnetic core is attractive. On the other hand, on the high frequency side including THz and optical frequencies, artificial magnetic materials may be more attractive than conventional magnetic materials.
