超穎材料在光科學開啟了嶄新的一頁，透過適當的設計，人們可隨意地操控其光學特性。為了能更全方位 地操控電磁波，實現立體化的等向性超穎材料是必須克服的難題。本文利用直立式裂環共振器組成一等向 性超穎材料，光譜研究顯示其在任何的平面旋轉、電磁波極化方向與電磁波入射角小於 30 度的條件下， 均顯示出其等向性之光學特性。

Metamaterials have led to a fresh prospect in optical science. One can engineer their optical properties arbitrary through a particular design. In order to control the electromagnetic waves completely, the realization of three dimensional isotropic metamaterials is an arduous problem to overcome. In this paper, we utilized the vertical-type split ring resonators to construct an isotropic metamaterials. The transmittance spectra reveal the isotropic responses for any lateral rotation, polarization and incident angle up to 40 degree.
