摘　　要：研究了由各向异性左手化材料和右手化材料构成的平板结构,利用传输矩阵方法,确定了平板结构的透射率和反射率.通过数值模拟方法,讨论了平板的厚度、组分的体积分数以及入射角对平板结构透射率的影响.结果表明,在结构厚度一定的情况下,对于不同的入射角,存在一个优化的体积分数,使结构的透射达到最大.同时垂直入时,透射效果最好.结果还显示了当结构的厚度足够小时,结构的透射既不依赖于组分的体积分数,也不依赖于入射角.此时透射率接近于1,表明结构可以实现全透.We investigate a slab composed of anisotropic left-handed material and isotropic right-handed material. By transmission matrix method, the transitivity of the slab can be obtained. By numerical calculation, the effects of the slab thickness, the volume fraction of the component and the incident angle on the slab transmission are studied. The results show that as the thickness of the structure is fixed, there exists an optimal volume fraction of the component for different incident angle, which leads the maximum transmission of the structure. When the incident wave is normal to the surface, we get the best transmission effect. When the thickness of the structure is small enough, the transmission of the structure is independent of both the volume fraction of the component and the incident angle. At the same time, the transitivity approaches to 1, which indicates the electromagnetic wave can fully penetrate through the structure.
