Abstract

We study the possibilities of using the eikonal equation to construct theoretical models of objects that become invisible under certain illumination conditions. The characteristics of the cloaking coating, which performs its functions for a given direction of wave incidence on the cloaked volume of space, are calculated. A method for constructing models of cylindrical objects that are invisible at arbitrary azimuthal and given zenith angles of illumination is proposed. It is shown that by employing the eikonal equation, it is possible to design invisible objects from materials with refractive indices of different signs.

论利用艾克纳方程构建隐形物体理论模型的可能性

我们研究了利用埃克纳方程构建物体在特定照明条件下隐形的理论模型的可能性。我们计算了隐形涂层的特性，该涂层在给定的波入射方向上对隐形空间体积发挥功能。提出了一种方法，用于构建在任意方位角和给定天顶角照明下隐形的圆柱形物体模型。研究表明，通过使用埃克纳方程，可以用折射率不同的材料设计出隐形物体。
