计算了木堆和反蛋白石光子晶体的三维色散关系。在适当的频率检查的等频表面的四个最低阶带，我们确定的区域，自准直的光可能是预期的。通过时域有限差分法计算高折射率和低折射率光子晶体，验证了这些预测。
We calculate three-dimensional (3D) dispersion relations of woodpile and inverse opal photonic crystals. Inspecting the iso-frequency surfaces of the four lowest-order bands at appropriate frequencies we identify regions where self-collimation of light may be expected. These predictions are verified by means of finite-difference time-domain calculations both for high- and low-index photonic crystals.
