通过实验和模拟，研究了一种由钇铁石榴石（YIG）片和金属丝组成的磁可调左手材料。通过外加磁场，左手材料的左手通带可以在很宽的频率范围内动态地连续调谐。通带的可调谐性归因于铁磁共振在YIG板中产生的负磁导率。提出了一种基于铁磁材料的可调谐左手材料（LHM）的设计方法，并通过实验和模拟验证了一种由钇铁石榴石（YIG）片和金属丝组成的可调谐左手材料（LHM）。通过外加磁场，左手材料的左手通带可以在很宽的频率范围内动态地连续调谐。通带的可调谐性归因于铁磁共振在YIG板中产生的负磁导率。作者提出了一种方便的方法来设计可调谐LHM的基础上的铁磁材料作为可调谐开口环谐振器的替代品。
A magnetotunable left-handed material (LHM) consisting of yttrium iron garnet (YIG) slab and metallic wires has been demonstrated by experiments and simulations. The left-handed passband through the LHM can be dynamically and continuously tuned in a wide frequency region by an applied magnetic field. The tunability of the passband is attributed to that of the negative permeability induced by ferromagnetic resonance in the YIG slab. The authors proposed a convenient means to design tunable LHM based on the ferromagnetic materials as an alternative to tunable split ring resonators.A magnetotunable left-handed material (LHM) consisting of yttrium iron garnet (YIG) slab and metallic wires has been demonstrated by experiments and simulations.
