中文摘要：

在TE10矩形波导中填充金属线阵和铁氧体合成了一种新型的左手媒质结构.分别使用了转移函数矩阵方法以及全波仿真工具AnsoftHFSS对所提出的结构进行了分析.结果表明,在横向磁化铁氧体等效磁导率实部为负的频段范围内,该合成结构呈现左手通带特性并伴随着后向波的传播现象.由于横向磁化铁氧体的等效磁导率为负的频段范围可调,故所提出的结构具有左手通带范围可调的特性.

英文摘要：

A novel left-handed material is proposed, which is composed of a metallic wire array in an X-band TE10 rectangular waveguide filled with ferrite. The proposed structure is analyzed by using the transfer function matrix technique and with the full wave simulation tool Ansoft HFSS. The results show that there exist left-handed passband and backward wave propagation phenomenon for the proposed structure in the frequency band in which the effective permeability for the ferrite transversely magnetized is smaller than zero, and the frequency band can be tuned by adjusting the externally imposed magnetic field and the ferrimagnet＇s magnetization, so we believe such a structure should provide medium-loss and tunable left-handed passband.
