| 摘 要： | 左手材料是一种人工合成材料，由于自然界中材料不可避免的寄生右手的特性，所以，在微波电路中，左手材料可演变成复合型左右手材料（composite right／left hand transmission line，CRLHTL）。左手材料由于可以实现负的介电常数占和磁导率肛，因此，电磁波在传输中群速和相速是反向的，左手材料已经得到物理界和工程界的巨大关注。目前，微波电路中的左手材料在理论、数值计算和实验方面得到了清晰的证实，而且得到了广泛的应用。

| Abstract: | Left-handed material（LHM） is a kind of artificial materials. In nature, a LH structure is impossible because of unavoidable parasitic RH property, so LHMs are considered to be a general model of composite right/left hand transmission line （CRLH） structures in microwave civcuits. LHMs with simultaneously negative permittivity （6） and permeability （μ）, which cause antiparallel between phase and group velocities, have attracted considerable attention both in the physics and engineering. At present, LHMs in microwave circuit, have been clearly confirmed on theoretical, numerical, and experimental, and have a extensive application. |
