金“nanograils”，新的等离子体纳米结构，可以表示为三个不同大小的环垂直连接的曲面，类似于一个小型化的圣杯，提出。反射率测量和FDTD模拟表明存在强的多个等离子体共振，具有相同的偶极对称周围的尖锐的环形边缘的纳米颗粒。
Gold "nanograils", novel plasmonic nanostructures that can be represented as three different-sized rings connected vertically by curved surfaces, similar to a miniaturized grail, are presented. Reflectance measurements and FDTD simulations demonstrate the existence of strong multiple plasmon resonances with the same dipolar symmetry around the sharp ring edges of the nanograils.
