本文从理论上研究了在外磁场中将Ⅱ型超导体中排列成二维三角晶格的Abrikosov涡旋看作电磁波光子晶体的可能性。由于周期性晶格上的布拉格衍射，具有与晶格间距对应的波长的电磁波不能在具有不同介电常数的Abrikosov晶格中传播。阐明了通过改变金兹伯格-朗道参数和外加磁场来获得Abrikosov晶格作为光子晶体的有效性质的条件。
The possibility of viewing the Abrikosov vortices arranged into two-dimensional triangular lattices in type-II superconductors in external magnetic fields, as photonic crystals for electromagnetic waves, has been investigated theoretically. Due to the Bragg diffraction on a periodic lattice, electromagnetic waves with wavelengths corresponding to lattice spacings cannot propagate in the Abrikosov lattices with different dielectric constants inside and outside the vortices. Conditions for obtaining effective properties of the Abrikosov lattices as photonic crystals by changing of Ginzburg-Landau parameters and applied magnetic fields are clarified.
