负折射率材料是指在一定频率范围内折射率为负值的人工结构。这些材料的研究在科学界引起了极大的关注，不仅是因为它们有许多潜在的有趣的应用，还因为由于描述它们的方程中的变号系数，在理解它们有趣的性质方面遇到了挑战。在本文中，我们建立了利用互补介质对电磁波进行隐身的方法。这证实和推广了Lai等人的建议。[物理。莱特牧师。102(2009)093901]，用于完整的麦克斯韦方程。分析基于反射和消除局域奇异性技术、三球不等式和麦克斯韦方程可归结为弱耦合二阶椭圆型方程的事实。
Negative index materials are artificial structures whose refractive index has negative value over some frequency range. The study of these materials has attracted a lot of attention in the scientific community not only because of their many potential interesting applications but also because of challenges in understanding their intriguing properties due to the sign-changing coefficients in equations describing their properties. In this paper, we establish cloaking using complementary media for electromagnetic waves. This confirms and extends the suggestions of Lai et al. [Phys. Rev. Lett. 102 (2009) 093901] for the full Maxwell equations. The analysis is based on the reflecting and removing localized singularity techniques, three-sphere inequalities, and the fact that the Maxwell equations can be reduced to a weakly coupled second order elliptic equations.
