For a one-dimensional (1D) anisotropic slab, if its electromagnetic parameters satisfy certain conditions, an incident wave can be totally transmitted without any reflections. In this work, a classical method based on analytical results and a transformation optics method using an arbitrary piecewise continuous transformation function are applied to design a 1D electromagnetic transparent wall, whose presence does not disturb the field distribution in the ambient environment. Material parameters and the geometrical requirement of the layered structure using these two different methods are derived, and they agree well with each other. Full-wave simulations validate the transparency of the proposed wall. Because of the simple constitutive parameters and geometry, a transparent structure could be realized using anisotropic and homogeneous materials. The proposed structure has potential applications in radomes, anti-reflection films, and various sensor sectors.
对于一维（1D）各向异性平板，如果其电磁参数满足一定条件，入射波可以完全透射而无任何反射。在这项工作中，基于解析结果的经典方法和使用任意分段连续变换函数的变换光学方法被用于设计一维电磁透明壁，该透明壁的存在不会干扰周围环境中的场分布。推导了使用这两种不同方法的分层结构的材料参数和几何要求，并且它们相互吻合良好。全波模拟验证了所提出的壁的透明性。由于本构参数和几何结构简单，可以使用各向异性和均匀材料实现透明结构。所提出的结构在天线罩、抗反射膜和各种传感器领域具有潜在应用。
