Conventional concentrators with inhomogeneous coating materials that fully enclose the destined region pose great challenges for fabrication. In this paper, we propose to design an EM concentrator with homogeneous materials. Distinguished from conventional ones, the elaborately designed EM concentrator features a concentrator region that is open to the outer-world, which is achieved with multi-folded transformation optics method by compressing and folding the coating materials to create window(s). Based on this concept, we also investigate open-rotator and open rotational-concentrator devices, which could simultaneously rotate and store the EM waves in the central destined region. Due to the open nature of our proposed designs, we believe they will find potential applications in remote controlling with impressive new functionalities.
具有完全包围目标区域的非均匀涂层材料的传统集中器在制造方面带来了巨大挑战。在本文中，我们提议设计一种具有均匀材料的电磁集中器。与传统的电磁集中器不同，精心设计的电磁集中器具有一个向外部开放的集中器区域，这是通过多次变换光学方法实现的，即通过压缩和折叠涂层材料来创建窗口。基于这一概念，我们还研究了开放式旋转器和开放式旋转集中器装置，它们可以在中央目标区域同时旋转和存储电磁波。由于我们提出的设计具有开放性，我们相信它们将在具有令人印象深刻的新功能的远程控制中找到潜在应用。
