采用频域全矢量紧致二维有限差分法研究了微结构光纤的色散和损耗。该方法直接从麦克斯韦方程组求解标准本征值问题，并利用各向异性完全匹配层获得模式的复传播常数。提出了一种利用安培定律的弯曲介质界面介电常数平均技术。该方法不仅可以获得复传播常数的真实的部分，而且可以获得复传播常数的虚部和实部。还讨论了材料损耗、色散和杂散模式。
The dispersion and loss in microstructured fibers are studied using a full-vectorial compact-2D finite-difference method in frequency-domain. This method solves a standard eigen-value problem from the Maxwell's equations directly and obtains complex propagation constants of the modes using anisotropic perfectly matched layers. A dielectric constant averaging technique using Ampere's law across the curved media interface is presented. Both the real and the imaginary parts of the complex propagation constant can be obtained with a high accuracy and fast convergence. Material loss, dispersion and spurious modes are also discussed.
