中文摘要：
平面EBG结构变换到曲面结构后，平面上仿真分析带隙的一些典型方法不再适用，如平面波反射相位法。为了得到曲率对EBG结构反射相位特性的影响规律，本文利用不同长度偶极子的回波损耗对应频带方法间接观察了曲率对反射相位的影响。结果表明，曲面EBG结构仍表现出良好的同相反射特性，与平面上频带相比，曲面上频带向低频稍微偏移大约400MHz，不同曲率半径时带隙范围相差很小。
英文摘要：
Some typical simulation analysis methods of electromagnetic hand-gap used on the planar, such as planar wave reflection phase method, are not suitable to be used on the curved electromagnetic band-gap structures. In order to obtain the effect of curvature on the reflection phase of electromagnetic band-gap structures, using the method of the corresponding frequency band of return loss of different length dipoles, the effect of curvature on the reflection phase is observed indirectly. The results show that, the curved electromagnetic band-gap structures still exhibit better in-phase reflection feature ; compared with the frequency band on the planar, the frequency band on the curved surface shifts to the lower frequency about four hundred MHz; the band-gap difference among different curvature radius is very less.
