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。
After the planar EBG structure is transformed into a curved surface structure, some typical methods of simulating the band gap simulation in the plane are no longer applicable, such as the plane wave reflection phase method. In order to get the influence law of the curvature on the reflection phase of EBG structure, the effect of curvature on the reflection phase is indirectly observed by using the corresponding band loss of the dipole with different length. The results show that the surface EBG structure still exhibits good in-phase reflection characteristics. Compared with the upper frequency band, the curved band shifts slightly to about 400 MHz toward the low frequency, and the difference of the bandgap ranges with different radii of curvature is very small.
