我们通过实验验证了微等离子体组装体可以作为“等离子体光子晶体”产生用于电磁波传播的功能介电层。在70- 75 GHz范围内，等离子体发射的微波具有能流方向的变化。这一结果归因于这样一个事实，即周期性结构是由具有不同于周围部分的色散的单个等离子体柱组成的，并且实验频率范围位于理论计算的光子晶体的最低带隙附近。
We experimentally verified that a microplasma assembly can create a functional dielectric layer for the propagation of electromagnetic waves as a “plasma photonic crystal.” A two-dimensional array in a square lattice was composed of columnar plasmas of about 2mm in diameter, and the transmitted microwaves at 70–75GHz showed a change of energy flow direction. This result is attributed to the fact that periodical structure is composed of individual plasma columns with a different dispersion than the ambient part and the experimental frequency range lies in the vicinity of the lowest band gap of the photonic crystal calculated theoretically.
