Plasmonic Graphene

我们开发了一个模拟软件，用于计算形成几百纳米孔阵列(纳米孔阵列)的金属薄膜的电磁波模式和光的反射和透射谱。揭示了三角形纳米孔阵列反射光谱出现凹陷的原因。我们还表明，蜂窝纳米孔阵列可以具有类似于石墨烯中的电子带结构的等离子体带结构。

We have developed a simulation software which calculates the modes of electromagnetic waves and the spectra of light reflection and transmission for the metal film where an array of holes with a few hundred nanometer (nanohole array) is created. We revealed the origin of the dips in the reflection spectra for triangle nanohole arrays. We also showed that honeycomb arrays of nanoholes can have plasmonic band structure similar to the electronic band structure in graphene.
