| 摘 要： | 使用有限积分方法对H型分形结构的电磁响应特性及其机理进行了计算机模拟，并与实验实测结果进行比较，证实了H型结构在很宽频域范围内具有准周期性多重电磁带隙，这种多重电磁带隙是由分形结构对入射电磁波的多重共振产生的．该结构与传统结构相比，具有尺寸小（远小于对应波长），易于加上，且不受传统电磁带隙结构周期性要求的限制等优点．

| Abstract: | This paper studied the electromagnetic characteristics of an H-shaped fractal structure.And the simulation result is achieved by Finite Integration Technique(FIT).The simulation results show a great agreement with the experiment results,exhibited that this structure has multiple band-gaps for electromagnetic waves in wild frequency region.The mechanisms of this structure were studied using FIT stimulation show that multiple band-gaps were caused by the multiple resonances in the fractal structure when the electromagnetic waves incidence.This structure can be fabricated easily,the size can be significantly smaller than the relevant electromagnetic band gap wavelength,and has no limitation of periodic demand compared to the conventional electromagnetic band-gap structures. |
