基于Menger海绵分形的局域电磁本征模的对称性，利用群论导出了其对光散射和透射的选择规则。用时域有限差分法计算了光的散射和透射谱，并与由偶极辐射谱得到的局域模的本征频率进行了比较。它们的对应关系相当好，支持数值计算的准确性和选择规则的正确性。
Selection rules for light scattering and transmission by the Menger sponge fractal were derived by the group theory based on the symmetry of its localized electromagnetic eigenmodes. The light scattering and transmission spectra were calculated by the finite-difference time-domain method and compared with the eigenfrequencies of the localized modes obtained from the dipole radiation spectra. Their correspondence is quite good and supports the accuracy of the numerical calculation and the correctness of the selection rules.
