研究了分形结构开口环谐振器的太赫兹特性。将Koch曲线的分形结构应用于SRRs，可以改变SRRs的电磁谐振频率。随着Koch曲线分形维数的增加，共振频率的位置向低频方向移动。这一结果表明，与工作频率下的波长相比，制造具有极小晶胞的超材料的可能性。
We investigate terahertz characteristics of split ring resonators (SRRs) with fractal structure. By applying the fractal structure of Koch curve to the SRRs, the electric and magnetic resonant frequencies can be modified. The position of the resonant frequencies shifts to lower frequency as the fractal level of Koch curve increases. This result shows the possibility of fabricating metamaterials with the extremely small unit cell as compared to the wavelength at operational frequency.
