本文提出了变换电磁学中空间不连续边界处折射异常的几何解释。基于射线追踪法分析了电磁波在空间不连续边界上的折射特性，并通过基于全张量各向异性介质等效电路的波传播仿真验证了分析的正确性。结果表明，在空间不连续边界的行为是几何解释的惠更斯原理和度量的变化，由于坐标变换的结果。
In this paper, a geometrical interpretation of anomalous refraction characteristics at a spatially discontinuous boundary in the transformation electromagnetics is presented. Refraction characteristics of electromagnetic waves at the spatially discontinuous boundary is analyzed based on the ray tracing method, and the validity of analysis is confirmed based on the wave propagation simulations based on the equivalent circuit of full-tensor anisotropic media. It is shown that the behaviors at the spatially discontinuous boundary is geometrically interpreted as a consequence of the Huygens' principle and the metric change due to the coordinate transformation.
