摘要 提出了一种曲折型缝隙加载的新型双带电磁带隙结构,这一结构可以在相同介质层中利用一种单元实现双带的表面波带隙。使用无限周期的色散能带图分析其表面波带隙特性并加工了电磁带隙结构样品。应用一对探针耦合的方法测量了该结构的横电波(transverse electric,TE)和横磁波(transverse magnetic,TM)模式下表面波带隙,实验结果表明:利用色散能带图分析的表面波带隙与测量数据基本吻合,验证了缝隙加载方法实现双带表面波带隙的可行性。 A novel structure with meandering slotted dual-band electromagnetic bandgap is proposed. The dual-band surface wave bandgap can be realized by using one kind of unit in the same substrate. The surface wave suppression bandgap properties were analyzed by using surface-wave dispersion diagram. This meander- ing slotted dual-band mushroom-like EBG structure was fabricated and the TE （transverse electric） and TM （transverse magnetic） surface wave suppression bandgap were measured by the use of a pair of coaxial probe for coupling surface wave. The results calculated by using a finite-element model are well agreed with the measured results. The feasibility is validated that dual-band surface wave suppressing bandgap can be realized by using slots.
