Motivated by investigation of black hole properties in the lab, some interesting subjects such as analogue gravity and transformation optics are generated. In this paper, we look for the analogies between the geometry of a gravitating system and the optical medium. In addition, we recognize that appropriate metamaterials can be used to mimic the propagation of light in the curved spacetimes and behave like black holes. The resemblance of metamaterials with Kerr and Reissner-Nordstrom spacetimes is studied. At last, we compare the full-wave numerical calculation of light with its optical limit of geometry.

超材料模拟黑洞：电荷和旋转对光学特性的影响

受实验室中黑洞特性研究的启发，产生了一些有趣的主题，例如模拟重力和变换光学。在本文中，我们寻找引力系统几何与光学介质之间的类比。此外，我们认识到适当的超材料可用于模拟光在弯曲时空中的传播并表现得像黑洞。研究了超材料与 Kerr 和 Reissner-Nordstrom 时空的相似性。最后，我们将光的全波数值计算与其几何光学极限进行了比较。
