三维任意斗篷的旋转分析

Revolution analysis of three-dimensional arbitrary cloaks

Guillaume Dupont, Sébastien Guenneau, Stefan Enoch, Guillaume Demésy, Andre Nicolet, Frédéric Zolla, Andre Diatta

摘要:

我们通过变换光学将径向对称三维隐形斗篷的设计扩展到具有旋转表面的斗篷。我们推导了变换矩阵的表达式,并证明了它的特征值之一在斗篷的内边界上为零,而其他两个保持严格的正的和有界的。我们的方法的有效性证实了有限的边缘元计算的非凸斗篷的厚度变化。

英文摘要:

We extend the design of radially symmetric three-dimensional invisibility cloaks through transformation optics to cloaks with a surface of revolution. We derive the expression of the transformation matrix and show that one of its eigenvalues vanishes on the inner boundary of the cloaks, while the other two remain strictly positive and bounded. The validity of our approach is confirmed by finite edge-elements computations for a non-convex cloak of varying thickness.
