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.
