运用平面波展开法模拟光子晶体光纤中的带隙结构

详 情 说 明

In order to simulate the bandgap structure in Photonic Crystal Fibers, the Plane Wave Expansion Method (PWEM) can be used. This method is a numerical technique that allows us to analyze the electromagnetic behavior of a periodic structure like a photonic crystal fiber. The PWEM technique can be used to calculate the band structure of the fiber, which is important in understanding its optical properties. Through the use of PWEM, we can analyze the propagation of light within the fiber and how the bandgap structure affects it. By understanding these concepts, we can gain insight into the potential applications of photonic crystal fibers in areas such as telecommunications, sensing, and biomedical imaging.
