详细和严格的理论研究的光学性质的一个通用的三维手征结构的等离子体球，没有和外部静态均匀磁场的作用下，提出。相应的光子带图与相关的透射谱，计算的全电动层多次散射方法适当扩展到的情况下，gyrotropic球形散射体，在光的非对称空间群的理论进行了讨论。这种分析提供了一个一致的解释，一些显着的功能和效果，如狄拉克点，偏振相关的传输，以及带分裂和非互易的光学响应，出现作为一个结果的时间reversalsymmetry破缺，由外部静磁场诱导，和缺乏空间反演对称的晶体。
A detailed and rigorous theoretical investigation of the optical properties of a generic three-dimensional chiral structure of plasma spheres, without and under the action of an external static uniform magnetic field, is presented. Corresponding photonic band diagrams in conjunction with relevant transmission spectra, calculated by the full electrodynamic layer-multiple-scattering method properly extended to the case of gyrotropic spherical scatterers, are discussed in the light of the theory of nonsymmorphic space groups. This analysis provides a consistent interpretation of some remarkable features and effects like Dirac points, polarization-dependent transmission, as well as band splitting and non-reciprocal optical response that emerge as a result of time-reversalsymmetry breaking, induced by the external static magnetic field, and the lack of space-inversion symmetry in the crystal.
