本論文探討漁網結構所具有的左手材料特性，只需週期性地堆疊金屬板(挖有比入射光波長還小的孔洞)，即可獲得具有光異常穿隧效應的左手性超穎材料。此外，調整漁網結構中孔洞直徑或是光傳遞方向的單位結構長度，可以輕易製作出具有右手材料特性或是左手材料特性的超穎材料。
將平面波入射至漁網結構超穎材料製成的稜鏡，計算入射和折射角度並利用思乃耳定律求出此超穎材料的折射率值，所得到的數值和理論計算出的折射率值相當符合。
一般想要在可見光頻段創造實用的元件，損耗是需要被解決且具挑戰性的問題，由於此漁網結構在本質上具有光的異常穿隧，便提供一種可以在可見光頻段降低金屬損耗的一種方法。

Our work demonstrates the feasibility of engineering left-handed metamaterials by periodic stacking of sub-wavelength hole array plates and brings together extraordinary optical transmission and left-handed behavior. Furthermore, we can achieve right-handed or left-handed metamaterials by adjusting hole diameter of metal plates or longitudinal lattice period.
We also verify the refraction index of fishnet metamaterials governed by Snell’s law is the same as theory calculation.
However, losses are one of the big challenges to be surpassed in order to design practical devices at optical wavelength. These fishnet structures exhibit inherently an extraordinary optical transmission which could offer a solution to the problem of losses at optical wavelengths.
