微等离子体的二维阵列形成“等离子体光子晶体”，其具有在体等离子体中不存在的新功能。证明了在电子等离子体频率以上的第一光子带上异常电磁波传播的两个特征。在电子等离子体频率附近，发生单向传播，并且在带隙附近在Γ-X方向上发生发散传播。这些现象在实验中得到了验证，细节也通过二维波数平面上的等频等高线得到了证实。（© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
Two‐dimensional arrays of microplasmas form “plasma photonic crystals”, which have new functions that have not been present in bulk plasma. Two features of abnormal electromagnetic wave propagation on the first photonic band above the electron plasma frequency are demonstrated. Near the electron plasma frequency, unidirectional propagation takes place, and divergent propagation occurs near the band gap in the Γ‐X direction. These phenomena are verified in experiments, and the details are confirmed by equi‐frequency contours on a two‐dimensional wavenumber plane. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
