本文数值研究了同时垂直和平行入射平面左手超材料（LHM）的负折射。这种左手材料由四个对称印刷在衬底两侧的C形环组成，在电磁波从三个不同方向入射时，表现出左手特性。反演结果和模拟结果很好地验证了四重C形超材料的左手特性。然后讨论了垂直入射和平行入射情况下金属导线对入射电磁波的不同电响应，这是由于感应电流在金属导线中的分布不同造成的。
We investigate numerically the negative refraction of a simultaneous normal and parallel incidence planar left-handed metamaterial (LHM) in this paper. This LHM is comprised of fourfold C-shaped rings, which are printed on both sides of the substrates symmetrically, and it can exhibit left-handed properties with electromagnetic wave incident in three different directions. The retrieved result and the simulated result verify the left-handed properties of the fourfold C-shaped metamaterial very well. Then the different electric responses of the normal and parallel incidence cases to the incident electromagnetic wave are discussed, and it is due to the different distribution of the induced currents in the metallic wires.
