几位作者最近展示了所谓电磁透镜领域的聚焦活动。这些透镜是超材料的平行板层，其特性可以用负折射率来描述。关于这个主题的已知作品涉及二维结构。这项工作是我们首次尝试展示 3D 超材料平行板层的聚焦效应，其近似分析模型之前已提出。传播的微带和焦点上的场分布与先前的理论在质量上是一致的。 (C) 2004 Elsevier B.V. 保留所有权利。
Several authors have recently exhibited the focusing activity in the domain of so-called electromagnetic lenses. These lenses are parallel-plate layers of metamaterials whose properties can be described in terms of negative index of refraction. Known works on this subject refer to 2D structures. This work is our first attempt to show the focusing effect by a parallel-plate layer of a 3D metamaterial, whose approximate analytical model was suggested before. The mini-band of propagation and the field distribution across the focal spot are in qualitative agreement with this previous theory. (C) 2004 Elsevier B.V. All rights reserved.
