摘要

理想情况下，锋利的边缘在计算上有些困难，但除了某些负材料参数范围外，该模型在理论上是合理的。在准静态极限下，负介电常数楔似乎支持具有无限能量的非物理边缘模式，这种理论异常在静态和动态模拟中都表现为无意义的数值结果。

Some computational aspects of too sharp edges

Ideally sharp edges can be computationally somewhat difficult, but the model is theoretically reasonable except for certain ranges of negative material parameters. In the quasistatic limit, negative permittivity wedges appear to support unphysical edge modes with infinite energy, and this theoretical anomaly show up as nonsensical numerical results in both static and dynamic simulations.
