Photonic band gap of a graphene-embedded quarter-wave stack
Yuancheng Fan, Zeyong Wei, Hongqiang Li +2
Here, we present a mechanism for tailoring the photonic band structure of a quarter-wave stack without changing its physical periods by embedding conductive sheets. Graphene is uti…
Toroidal Response in Dielectric Metamaterials
Alexey A. Basharin, Maria Kafesaki, Eleftherios N. Economou +1
We present and analyze a dielectric cluster based on subwavelength LiTaO3 polaritonic cylinders for demonstrating toroidal response in THz regime due to mutual coupling of Mie- res…
Enhancing Optical Gradient Forces with Metamaterials
Vincent Ginis, Philippe Tassin, Costas M. Soukoulis +1
We demonstrate how the optical gradient force between two waveguides can be enhanced using transformation optics. A thin layer of double-negative or single-negative metamaterial ca…
