中文摘要：
利用光学Bragg反射条件，设计了一种曲面电磁带隙结构。采用悬置微带线法，分析了其结构参数以及圆柱结构参数对带隙特性的影响。结果表明，结构参数对表面波带隙影响的规律与平面上一致，圆柱曲率对表面波带隙的影响不是太大，只是带隙中心频率略有下降。这一结论对在曲面共形天线上应用电磁带隙结构提高天线性能有重要的指导意义。
英文摘要：
According to the reflection condition of optics Bragg, a curved surface EBG structures is designed. Using the suspending microstrip method, the effect of EBG structure parameters and cylindrical structure parareeters on band-gap characteristics are analyzed for the first time. The results show that the effect of structrue parameters on surfaces wave band- gap is in agreement with the effect of planar structure parameters, the effect of curnature on surface wave band-gap is lesser, and the center frequency of band-gap has a little decrease. These conclusions have some certain important guided significance to apply EBG to curved surface conformal antennas in order to improve the performance of antenna.
