变换光学中的反问题

Inverse problem in transformation optics

A. V. Novitsky

摘要:

变换光学的直接方法是从坐标变换出发,确定隐身衣的雅可比矩阵、场和材料参数。然而,坐标变换似乎是一个可选的功能:它是没有必要知道它。我们提供了某种反问题的解决方案:从隐形斗篷中的场开始,我们直接推导出隐身外壳的介电常数和磁导率张量。该方法可用于在不知道坐标变换的情况下求出隐身壳体中特定电磁场的材料参数。

英文摘要:

The straightforward method of transformation optics implies that one starts from the coordinate transformation, determines the Jacobian matrix, the fields and material parameters of the cloak. However, the coordinate transformation appears as an optional function: it is not necessary to know it. We offer the solution of some sort of the inverse problem: starting from the fields in the invisibility cloak we directly derive the permittivity and permeability tensors of the cloaking shell. The approach can be useful for finding material parameters for the specified electromagnetic fields in the cloaking shell without knowing coordinate transformation.
